Extensions Won't Enable

[bigealien]

Same here.

Disable phpBB SiteMaker extension.

Ok cool - that is an easy fix and I will do that! Can you tell me what browser you are using on what kind of device?

Despite such an easy fix I cannot disable the extension or ANY extension and cannot enable any extension due to the issue that this thread is originally about. Does anyone have any advice on this? I cannot find anything related to an answer anywhere else.

Not sure if this will help: Knowledge Base - Disabling all extensions at once? Presumably you should make a db backup before trying it.
