Upgrade clicked, fatal error, all admin CP lost :(

[Ciel!]

I went to upgrade the new install, it got partway through, then I got this:

 

Fatal error: Access to undeclared static property: IPS\Theme::$defaultThemeSet in/home/mythandm/public_html/init.php(435) : eval()'d code on line 26

 

Now, I cannot access the Admin CP at all, and am stuck. Please help!

Submit a critical ticket.

I submitted a support ticket just now, but no idea where I can mark it "critical". I don't think I have that option, unless I'm oblivious and missing it.

There's an option on submit form. You should check it if your board is inactive due to an issue.

This was resolved via a ticket and was due to a third party plugin.

THANK YOU to IPS for fixing!

 

PS to the rest though - I do not have that "severe client issue" option when submitting my tickets.
