Unknown Error

Hi; I upgraded my local MW to 1.43.1 (on windows 10) and installed master version of MsUpload. But or any upload i get "Unknown Error", although the file is correctly loaded. How can I debug the extension; the global error.log is full ot messages and i can't see anything relevant. 2A01:E0A:44F:F9E0:7120:44F1:9621:CFE9 13:49, 25 May 2025 (UTC)

Where does it say 'unknown error'? Have you upgraded the WikiEditor extension as well? Does the upload button work or drag-and-drop (or vice versa)? I've got it working on 1.43 without issue, so it does work at least in some configurations! :) Sam Wilson 03:39, 22 June 2025 (UTC)

I also have problems with MsUpload when upgrading from MediaWiki 1.39 to 1.43.1/1.43.2/1.43.3. When I try to upload pictures with my Firefox-Browser, drag an drop works but as soon as I click on "Upload" nothing happens. The screen ist still showing the former screen. When I tried the same with the Microsoft Edge-Browser the extension works without problems. TS (talk) 13:22, 7 July 2025 (UTC)

File Descriptions

This extension is extremely useful, except for one issue: I can't seem to figure out how to change the default behavior of having the file descriptions be nothing but "File uploaded with MsUpload". I figure there has to be a way to set some setting or variable that would enable custom descriptions, but I can't find it. Having every single description being identical "File uploaded with MsUpload" is obviously not useful and defeats the whole purpose of having a description in the first place. At the moment, I'm working around by either doing manual uploads, or by running a bot to add the descriptions and categories afterwards (I can input the exact text strings for each description into the computer program all at once, and then "unleash" the script on my wiki and it will add them all automatically). But, both of these are a lot of work, so they're not ideal. Unfortunately this is the only bulk upload extension that would suit my needs, as the original special page-based MultiUpload I gather is broken without a maintainer, and UploadWizard seems too WMF-specific and too difficult to configure for a single wiki.

@The Boston Railfan: You can edit the msu-comment system message. I've now added this info to the docs in Extension:MsUpload#Extension_features. Sam Wilson 23:10, 31 January 2026 (UTC)

Sorry, I meant how do you supply a custom description for each file while performing a bulk upload? Most times when uploading each file needs its own unique description, yet it's still important to be able to upload more than one file at once. The Boston Railfan (talk) 00:23, 1 February 2026 (UTC)

@The Boston Railfan: Ah right, yep that would be good! Can't be done at the moment, but I'd recommend opening a Phabricator task to request it. Sam Wilson 03:05, 1 February 2026 (UTC)
