XF 1.4 Guests can register anymore => error URGENT

[Betclever]

Dear all,

I have a critical issue...
Guest users can't register anymore, they receive this :

A server error occurred. Please try again later.

I also notified that i don't have the option to validate users anymore...

Can someone tell me what I can do to solve this issue?

I have this as error in the logs:

Zend_Db_Statement_Mysqli_Exception: Mysqli statement execute error : Field 'competition_entries' doesn't have a default value - library/Zend/Db/Statement/Mysqli.php:214

[Mr. Goodie2Shoes]

Do you have any add-on related competition and if yes, is it disabled by any chance?

 

[TPerry]

And if you don't have any add-on related to competitions, did you have one installed at sometime? If so, the uninstall may not have been clean and you need to re-install that add-on and make sure it removes all the entries that it makes - some uninstalls can have problems and not be clean. There are also three other add-ons listed in there.
One involving New user convrsations, one involving TAC DeDOS, and finally ******* Credits.
