MyBB SQL Error
MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
145 - Table './sampsrvv_Potlood/mybb_sessions' is marked as crashed and should be repaired
Query:
DELETE FROM mybb_sessions WHERE ip=X'6b8d5c97'
Please contact the MyBB Group for technical support.

can you log into forum admin panel with direct link ? if so you can try repairing the tables from admin panel

admin panel >> tools & maintenance >> Task Manager --> Tables Check --> find a clock like icon next to it and click on it

if that doesn't help then you have to log into your web host control panel, navigate to database manager program (eg. phpMyAdmin)
and run SQL for the forum database

REPAIR TABLE mybb_sessions

see if required => SQL queries guidance
