I've just upgraded to 4.3 beta and I can't get into my admin and I'm thinking its due to a 3rd party plugin/application.

Is there a way I can disable the apps outside of the Admin area?

This is the warning I get when I try to log into my admin area:

SELECT * FROM `core_members` WHERE 
IPS\Db\Exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1 (1064)

Thanks in advance. 

 

We will be pushing out a patch or new beta release soon to address this issue. It is unrelated to any third party plugins you may have installed.
