How do I deactivate my account on this forum?

[SpaceTech]

I tried to deactivate my account but the button gives me the error

" Oops! We ran into some problems.
The requested page could not be found. "

I won't test it to see if it works for me, as that could end badly.

Admin do look in this forum so might notice the error and be able to fix it, as its above my non existent pay grade
