Error message when uploading media files to this forum

I get an error message when trying to upload photos and videos (of accepted format) to this forum.
The upload message progresses to 100%, and then I get a pop up saying:
“Sorry, there was an error uploading that file. Please try again.”

I’m accessing the forum via Firefox beta 96.0b3 (64-bit) installed from flatpak.
Is this the expected behaviour, or have I encountered a bug?

I can imagine that has something to do with your trust level. As in the following topic you can see when trust-levels alias user rights are changed manually the error-messages are incorrect.

No obvious place in the #start-here category does it say this forum does not accept photos or videos. I mean, it’s reasonable to prefer text based communication over large files, but it should say so somewhere, as well. What is the maximum allowed file size, and does it depend on trust level?

My trust level is Basic User, aka TL 1. According to Discourse I should be able to upload files… I can’t recall having my trust level manually altered.
As an aside, when I check my messages there are none from discobot. How do I get the user tutorials/badges without them?

This error message implies that trying again will make it work. I spent an hour in the middle of the night figuring out how to use kdenlive to edit a screen capture video i made of the issue using OBS studio, and converting it to a gif afterwards. Time which would probably have been better spent sleeping. :sweat_smile:
If the forum behaviour is not a bug, it would be good to change the error message so others won’t spend time trying again.

What browser are you using please? Do you have add-ons etc. installed that may be blocking javascript and so on?


I do have ublock origin installed in firefox, but I’ve set it to allow all javascript on this website. There are also some other privacy related addons which might affect forum behaviour. I’ll check when I get home in a bit.
Uploading a screenshot by accessing the forum via Fennec (libre firefox) on my android phone seems to work:

So it might be related to flatpak or one of the extensions/addons I have installed on desktop firefox.

Try temporarily disabling your extensions or temporarily switching to empty Firefox profile.

If that doesn’t work, since you are using an unreleased browser in beta testing, can you try a different browser and see if the problem persists?


I don’t think there is anything out of the ordinary in in the site configuration that should prevent uploads, and screenshots and even videos of a problem seem reasonable to have (hopefully at least accompanied by search- and accessibility-friendly text).

I’ll look in the logs and see what I can find. @ruzko, can you give details of exactly the media you were trying to upload, and the exact time it failed (try again if you didn’t record that the first time) and I’ll forward it to Discourse support. Thanks!


FYI, I was able to upload with the firefox beta flatpak with no extensions.


I am able to upload files when firefox is in troubleshooting mode / all extensions are disabled.
This confirms that the problem is probably due to my particular mix of extensions.

Will continue testing to find the offending extension

*Edit 1: If I disable all extensions, upload a file to a comment, then enable all extensions again before posting the comment, the file will still be posted.


Found it by method of elimination. ClearURLs 1.21.0 blocks uploading of files to this forum, somehow.
I created an issue concerning this here

Thanks for all your help and suggestions :slight_smile:
