since our templates are from the same kind (see my thread), I think the reason
has to be found in our template code structure. its very strange that yootheme
templates seem to be not working at random with youjoomla popup-login module, some do - some not ... indepently from the release date. yootheme in general have very cleaned-up code and i am also using the july09 template overrides.
try to comment out the call from index.php to lib/....mootools.js
by doing so the popup appears. unfortunately all the ajax does not yet work.
so if the people type in a wrong password or invalid username in registar nothing
Neo, where are the ajax verification and popup-messages executed and with
what could they be messed up?
have a nice day
