I've had problem with editing the vhost templates with the built in editor, where it converted some characters into something else and broke the website. I couldn't duplicate the error again, though I didnt try hard enough to duplicate.
But, the language editor is definitely broken. Editing a language, let's say User - EN - domains. Just by saving it without doing nothing will wipe away everything after
DOMSSLSUCCESS="Domain
. It also, doesnt want to keep the
+
sign in the FTPALFNUMSIG line.
Check out your demo1 panel. The domain edit for user panel is now visually broken.
