MyBB Community Forums

Hello. I'm new here, and I have a problem with my forum
When I try to enter any forum/category, this error pop-ups

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
    144 - Table './admincentar_net/mybb_posts' is marked as crashed and last (automatic?) repair failed
Query:
    SELECT tid,uid FROM mybb_posts WHERE uid='55' AND tid IN (6778,5797,7222,6950,7228,7226,7188,7110,6258,6260,6259,6873,6812,6928,6824,6802,6417,6953,6844,6909) 

What should I do?

Run this query in phpMyAdmin:

REPAIR TABLE `mybb_posts`;

Thank you for express reply. I'm not main administrator, so when I get in touch with main one, I'll let you know if there's no bug anymore.

Its worked now.. Thanks
