What i did:

Adminconsole, settings, UI tab

changed "Admin Console Template" to "Help"

Saved

After that all adminconsole pages are blank.

 Tested the same on the demo, same result.

What to do?

ok if you have db acces try:

mysql>update settings set value="PBtmpl0000000000000001" where name="AdminConsoleTemplate"; 

it worked for me

well settings is the most logical table, then the name should be related to the Admin console template.

Finally I looked in another instance of WebGUI (it was another version: 7.3.22) to lookup the value. The most essential names do not change that often.

There should also be a mysql log somehere, but since it worked immediately, I didn't have to use it. Not sure what the log format is, so whether that would have done it, I don't know.
