Hi - I am encountering an "Internal Server Error: The server encountered an internal error or misconfiguration and was unable to complete your request." problem when editing template pages in "source editor" mode. It is really odd: it seems to happen only when pages get to a certain length, and it only impacts "source editing" mode and not "visual editor" mode, so I can generally get around it, but not when editing templates as they don't give you the visual editor option (why is that by the way?)
It seems to be mediawiki related as it comes up on different machines, different browsers and on mobile as well. Is it something i have done? ElectricRay (talk) 14:16, 5 June 2023 (UTC)
