I edit a lot of the pages for the Dicey Dungeons wiki, but currently have issues uploading image files larger than 12 KB (i.e. an image file) as well as making any new wiki pages larger than 12 KB. Does anyone know how this can be fixed?
When I try to upload big files, the issue just shows as "Failed" without any actual reason given. When I try to make a wiki page larger than 12 KB, the edit page just resets itself back to the original version before upload without any changes being made, regardless of if I select "Save", "Preview", or "Cancel".
I'm not the owner of the wiki so I don't have access to any configuration files, but it might have happened because of some incompatibility with PHP8. I'd like to at least know what some possible causes could be. This issue started around 2023/03/01.
