Hallo, Platonides,
Du meintest am 20.07.11:
I've just tried to edit one of my wiki pages and have got the message
Detected bug in an extension! Hook ConfirmEditHooks::confirmEditMerged has invalid call signature; Parameter 1 to ConfirmEditHooks::confirmEditMerged() expected to be a reference, value given
(...)
You have an old version of ConfirmEdit. Just update it to the latest version, appropiate for use with MediaWiki 1.17.
Thank you - updating solved the problem!
Viele Gruesse! Helmut
