manque des explications
Il manque probablement une partie des explications, car, après avoir suivi toutes les instructions, on n'obtient rien d'autres que des images noires ou des erreurs d'affichage quand on clique sur l'onglet image. J'ai essayé une installation sur internet et sur mon ordinateur, et c'est tout ce que j'obtiens à chaque fois. Mode41 16:23, 6 May 2010 (UTC)

How to perform steps 3 and 4?
Forgive the beginner, but how does one execute the SQL file? I tried executing ProofreadPage.sql in the command prompt and got nothing. And what about #4: am I correct in assuming that that is telling me to edit ProofreadPage.sql to use the correct prefix?

I'm assuming that my failure to complete these two steps is what caused me to get the error:
 * Database returned error

Can anyone help? --Spangineer 04:26, 7 February 2011 (UTC)
 * Two ways :
 * run update.php, or
 * copy/paste the sql file content in phpmyadmin.

Proofread error: "no such file"
Hi, technical question.

I've tried to install Proofread on a fresh MW site, and it gave the error above every time I tried to make and index page (source came from archive.org and uploaded fine, even though no thumbnail on the File description). I've done this several times in id.wikisource too, so I'm stuck with this error for more than a year now. Anyone can help me?

I've added new namespaces (100-103) and updated the database, but I've got the following error when I saved the index page:

Ada kesalahan sintaks pada permintaan basis data. Kesalahan ini mungkin menandakan adanya sebuah bug dalam perangkat lunak. Permintaan basis data yang terakhir adalah:

dari dalam fungsi "". Basis data menghasilkan kesalahan "1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '0,0,0,0,0)' at line 1 (localhost)".

Even though it generates error, the index page was saved sucessfully. But it gave the "Error: no such file" message like the one in Index:Federal_Cases,_Volume_19.djvu. While the File:Federal_Cases,_Volume_19.djvu was corrupt in this case, mine was okay. So again, I don't know what's wrong with my installation.

Many thanks before. Bennylin (talk) 13:15, 2 January 2012 (UTC) (crossposted from English Wikisource's Scriptorium)

No Image
I installed the extension on my wiki but when I create a Page:xyz.jpg there is no image at the right side. Via Scan I can see the image. What's wrong? --87.146.17.135 13:10, 4 November 2012 (UTC)
 * You may have not well configure support for pdf, tiff or djvu files. Tpt (talk) 16:43, 4 November 2012 (UTC)
 * these extensions working fine.. --87.146.7.92 18:30, 4 November 2012 (UTC)
 * I'm having some trouble with the "Image" tab in the "Page:" namespace. It returns a 404 error. I've added to the Apache rewrite rule to the .htaccess in my MediaWiki folder, but this continues. --Inops (talk) 23:59, 4 November 2012 (UTC)
 * Are you using InstantCommons ? If you give me error messages you see and format of files you use, it would be better. Tpt (talk) 08:25, 5 November 2012 (UTC)
 * Am I not using InstantCommons (I was thinking for using it though, does it have an adverse affect on the extension?). I am attempting to use the extension with a PDF file, the extension functions perfectly well with PDF otherwise (I don't require the use of .djvu), but this error is a minor ningle of mine. The "Image" tab returns a generic 404 error (the displayed messaged dependant on the browser, obviously).
 * The URL of the tab e.g. "/mediawiki/images/thumb/1/13/Example.pdf/page10-1275px-Example.pdf.jpg", this returns a 404 error. However, "/mediawiki/thumb.php?f=Example.pdf&width=1275&page=10" will return the JPG rendering of the specific page of the file, and thereafter "/mediawiki/images/thumb/1/13/Example.pdf/page10-1275px-Example.pdf.jpg" will correctly return that image.
 * It seems that "mediawiki/images/thumb/" often produces the error, but "mediawiki/thumb.php?" does not, and does rather fix the former's error in a particular example. I assume this is to do with the creation of the thumbnail in the installation; thumb.php? creating the thumbnail and /thumb/ recounting the thumbnail. If the tab hyperlinked to the thumb.php address, this wouldn't be an issue. Is there a fix to this? Thanks, Jordan. --Inops (talk) 12:21, 5 November 2012 (UTC)
 * It's maybe because you haven't well configure thumb system. If you add the URL rewriting configuration describe there I hope that will solve your problem. Tpt (talk) 09:05, 6 November 2012 (UTC)
 * I've tried the code you suggested, but this didn't seem to make a difference. I've decided to disable the broken (for me) function by disabling the code in ProofreadPage/ProofreadPage.body.php. Thanks for the help. :) --Inops (talk) 09:54, 6 November 2012 (UTC)

5050 error on save
I'm unable to save any page in the Page namespace. It returns a 5050 error. So, the extension is rendered useless. My error log gives:
 * [07-Nov-2012 18:17:02] PHP Fatal error: Undefined class constant 'READ_LATEST' in D:\www\mediawiki\extensions\ProofreadPage\ProofreadPage.body.php on line 1238

Though, I am not sure if that's anything to do with it. Any help with this would be great. 90.220.162.151 18:22, 7 November 2012 (UTC)
 * It's a constant that is introduce in MediaWiki 1.20, version that have been release today. So upgrade your MediaWiki installation to MediaWiki 1.20 will fix the problem. If you don't want to upgrade to 1.20 you can remove ", Revision::READ_LATEST" from the line 1238 of the file D:\www\mediawiki\extensions\ProofreadPage\ProofreadPage.body.php and it will work (but can introduce a bug if two people save the page as the same time).
 * Thanks! Works perfectly. I had to install a newer version of Extension:Vector though. 90.220.162.151 00:25, 8 November 2012 (UTC)

Localization
How to add new translations of the namespace-names? I don't see it on translatewiki. --Bjarki S (talk) 01:20, 19 January 2013 (UTC)
 * I've updated translatewiki:Translating:MediaWiki. In short, you can now file a request on bugzilla, MediaWiki extensions>ProofreadPage. Previously all wikis had to configure it locally. --Nemo 06:43, 19 January 2013 (UTC)

Alright. Thanks! --Bjarki S (talk) 20:58, 19 January 2013 (UTC)

no such file at wikilivres
The Wikilivres.ca website has been getting the "no such file" errors reported here at Proofread error: "no such file" for maybe six months. Could anyone here suggest a solution? Please see wikilivres:wikilivres:Community_Portal/en for examples of files with the problem, together with links to a database error occurring when the pagelist tag is used. Thank you. -84user (talk) 23:04, 19 January 2013 (UTC)
 * Are you sure that DjVu support is well configure on your server ? I think that this is the cause of the issue. See DjVu for more information. Tpt (talk) 20:29, 20 January 2013 (UTC)

OCR software
I can't seem to find any information on the OCR software that this extension uses. We have just finished setting this up on the Icelandic Wikisource but there is a marked difference in the quality of the OCR retrieved from an English test document and an Icelandic one with the same font and font size. I am wondering if the support for the Icelandic language is not built into the OCR software or if there are any ways to improve it. Does the software learn by itself to recognize strange new characters like þ and ð if given enough practice or would that be a waste of time and effort? --Bjarki S (talk) 04:59, 20 January 2013 (UTC)
 * The extension doesn't include any OCR software, it only extracts the text embedded in the PDF/DjVU files you're using: check what generated them. s:en:Help:DjVu files has a lot of advice on how to get DjVu with decent OCR; for instance, if you use archive.org don't forget to specify the language of the document in your metadata. --Nemo 09:44, 20 January 2013 (UTC)
 * Hmm. So what does the "OCR" button do? Seems to work fine with PDFs without embedded text layer. --Bjarki S (talk) 17:15, 20 January 2013 (UTC)
 * My information may be outdated, but are you sure it's a PDF without text or is just your PDF reader unable to read/select/copy it? pdfinfo or pdftotext commands would tell you. --Nemo 18:00, 20 January 2013 (UTC)
 * OCR button is managed by a script stored on oldwikisource that call a script on toolserver that use the free but not very good Tesseract OCR software configured for the English language. So, if you use the script on an English and on an Icelandic texts, it's normal that the OCR is better for the English one. Tpt (talk) 20:34, 20 January 2013 (UTC)
 * Alright, thanks! Seems like there is no free option available for Icelandic. --Bjarki S (talk) 04:18, 29 January 2013 (UTC)
 * Eh, there are options available for Icelandic. There are three online services that have icelandic OCR support: Archive.org, ocr-extract.com and newocr.com. Plus, there is an Icelandic language file for Tesseract on Google code, and that is enough to make Tesseract compatible with Icelandic.--Snaevar (talk) 15:50, 29 January 2013 (UTC)
 * I installed support for icelandic on the toolserver, as for all language with diacritics accuracy of results depends a lot on the quality of scan. Beside that I also upgraded tesseract, result should be a bit better for all supported language. Phe (talk) 22:29, 30 January 2013 (UTC)
 * Hi, I'm a newbie on this, so forgive me if my Q's are too simple. I've uploaded this file:http://commons.wikimedia.org/wiki/File:ChFSA_FD1197205170%281%29.djvu, which is in spanish. The Proof Read Page doesn't seem to catch the OCR. I converted the .djvu, using Any2DjVu (Medium (300 dpi); Lossless; OCR (only works reliably for english text, locate columns automatically.)), at this point I really don't care about the quality of the OCR ('cause in Spanish), but that the proof reader page program actually performs the transclution to the Wikisource page, I'm doing sometihg wrong here? Thanks!--3BRBS (talk) 04:20, 2 February 2013 (UTC)
 * Hi! If I've well understood what your are saying, the issue is that you doesn't manage to get the text layer of the djvu (that contains a text layer) when your tired to get create pages of the Page: namespace? If yes, It's very strange because this extraction of the text layer of this file works fine for me on my test wiki. Tpt (talk) 15:57, 2 February 2013 (UTC)
