@Null I am receiving an error uploading images. Just a few minutes ago I uploaded one just fine, but the second gives errors, even with "ignore warnings" checked. MediaWiki does in fact create the File: page , and does upload the actual image itself. File page with error - https://lolcow.wiki/wiki/File:ADF-amaterasu-death-DID-system.png Actual image - https://lolcow.wiki/wiki/images/3/3a/ADF-amaterasu-death-DID-system.png While fiddling, I noticed that sometimes when I "Choose image...", a thumbnail will not be created before I submit. I presume that is where the error is happening. If I make sure it creates the thumbnail, an image uploads fine, of course. Scratch that. Sometimes it fails anyway. Re-uploading the same image over the broken one, even if I allow the thumbnail to load, doesn't fix the problem. Deleting the busted image I uploaded would work as a temporary fix, but I don't have access to do so. Correcting this error might fix some of the other thumbnail errors that are happening on various pages.
