Topic on Project:Support desk

I recently install mediawiki and have not had any issues creating and editing wiki pages until I attempted to upload a new image to the wiki server. I used the upload file page, after I browsed to my 60k image I selected upload file. After that I received a 500 error. I also get this on any page that attempt to view the image. Gallery of new files, File lists.. etc.

Error:

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

I've check my permission on the following files to try and fix the issue.

C:\php\ IUSR Permission Full Control
C:\inetpub\wwwroot\wiki\images IUSR Permission Full Control

I can also see the image in C:\inetpub\wwwroot\wiki\images\e\e5 Any ideas of how to fix this issue.

System Information:

MediaWiki: 1.19.2
PHP Version: 5.4.6
MySQL: 5.5.27
OS: Windows Server 2012 Enterprise
Web Server: IIS 8

LocalSettings.php

$wgUseImageMagick = true;
$wgImageMagickConvertCommand = 'C:\Program Files (x86)\ImageMagick-6.7.9-Q16\convert.exe';
$wgEnableUploads = true;
$wgFileExtensions = array('png', 'gif', 'jpg', 'jpeg', 'doc', 'xls', 'mpp', 'pdf', 'ppt', 'tiff', 'bmp', 'docx', 'xlsx', 'pptx', 'ps');
$wgMimeDetectorCommand = "file -bi";
$wgHashedUploadDirectory = false;
$wgCacheDirectory = "$IP/cache";  

I also created an error log by adding show exceptions and debuglogfile option.

$wgShowExceptionDetails = true;
$wgDebugLogFile = 'C:\inetpub\wwwroot\wiki\error-debug_log.txt';

I'm not seeing a smoking gun in the log, so would this mean a permission issue?

Here's the log output from when I tried to upload a new image.

I was able to figure out what the problem was. The problem in my case was related to how IIS was configured for FastCGI. In the FastCGI settings section of IIS I noticed that the Max Instances was set to 0. I increased the value to 4 and it worked. I'll need to adjust this setting more to find the sweet spot.

Hi, I have the same problem.

I uploaded a file and it encountered the 500 - Internal sever problem. I can see the image which is within the link of the file (e.g. /roots/images/3/image.png) However, I cannot view the "File:image.png" and it return 500 - Internal sever problem!

It is very frustrated. Could you please tell me is it similar to your problem?

Thanks,

Make sure you grant Modify rights to the upload folder for the IISUser account.

I am using Mediawiki 1.26.4 with PHP 5.4 I SOLVED the problem by switching on XMLREADER in the php version via cpanel after seeing the error in the error log which is stored in the Mediawiki directory on my website.

Hope this helps !
