Something has gone wrong.

zoof

I have a vanilla forums site that appears to be dead. The only thing I can think of is that a relatively recent upgrade to php 7.4 is responsible but I don't know. After turning Debug on, I get:

Table 'vanilla.GDN_Permission' doesn't exist
The error occurred on or near: /var/www/vanilla/library/database/class.database.php
403:                 // If we get here then the pdo statement prepared properly.
404:                 break;
405: 
406:             } catch (Gdn_UserException $uex) {
407:                 trigger_error($uex->getMessage(), E_USER_ERROR);
408:             } catch (Exception $ex) {
409:                 list($state, $code, $message) = $pDO->errorInfo();
410: 
411:                 // If the error code is consistent with a disconnect, attempt to retry

Any ideas?
