[1.1.3] registration broken


Hi there,

I´ve upgraded my 1.1 to 1.13 yesterday. Since that (but not necessarily caused by the upgrade) users can´t register anymore. The login for registered members just works fine, only the registration seems to be broken and leads to a XenForo Error page, stating "We encountered a server error. Please try again later."

The corresponding error logs show this:
Error information:
ErrorException: Declaration of CemZoo_Username_DataWriter_User::_verifyUsername() should be compatible with that of XenForo_DataWriter_User::_verifyUsername() - library/CemZoo/Username/DataWriter/User.php:102

I changed Captcha from Re-Captcha to manual Captcha yesterday because of spamrobots, which can obviously pass the Re-Captcha and installed 3 other AddOns (with TMS). I disabled all AddOns and even with reenabled Re-Captcha, the registration won´t start to work again.

Honestly I don´t have an idea, what this error log is trying to tell me. Exept, that the library file User.php seems to have a mismatch on line 102 - and thats the last sign of that file: a closing } .

A little help would be appreciated :confused:

Looks like from the error to be caused by an add-on called CemZoo Username Changer?

Disable that first, see if the problem persists or not.


Noticed that too. I was using the very first unpaid release. I´m still in the process of setting the site up so may be I´ll make use of the paid one later on and disabled this one for now. Anyway thanks for the heads-up, I´ve contacted the author already.
