Error 500 when editing Adventure Lab

[+~Poseidon]

Hi all.

 

I am trying to edit a stage of my adventure lab, but I get the following 500 error when I do:

 

 

This happens whether it is a stage of the lab or the lab itself that I edit. It happens on all 3 of my adventures. It happens on Firefox, Brave, Chrome and Edge. This used to work.

 

I thought GCHQ should be aware of this problem. Has anyone else experienced this?
