Hello,
I use CB 1.7 with joomla 1.5.23. I've upgrade it from CB 1.4 with the installer. I did not delete the CB 1.4 before because the manual dont say something like that.
With CB 1.7 I recognized a problem with the email checker in the backend. When I want to change some Userdates an go to the save-button, CB shows "error" in the email checker.
I know that there a some problems with this in CB 1.4.
BUT, this error only appears in firefox 5. I tested it with IE 7 and IE 9, the are no problems. With Opera 11.5 I cant't see any check process.
The changes will be stored in the datebase anyway. The database is ok, too.
