Unable to reach dashboard, memory at 256, Can't get in to clear cache. Please Advise

Greetings, We have a legacy installation that we neglected to clear the cache on in time and now we are unable to get to the admin to clear.

I have ssh into and searched for hidden files in the cache directory, but have found none.

I did make sure memory is set to 256

I am seeing this error in the error log

PHP Fatal error: Cannot unset $this in /home2/aislesev/public_html/c5/updates/concrete5.5.2.1/concrete/libraries/3rdparty/adodb/adodb-xmlschema03.inc.php on line 178

Is there a way to manually clear the cashe?

How can I get to the dashboard?

Here is my php.info

My c5 installation is in that same folder

Any help is much appreciated!

Got it! Turns out we had a php upgrade and it broke the legacy installation.

I think hosts that automatically upgrade PHP without at least a month's warning and break a bunch of sites need to be sued.
