I think that we never had it before. Our forum(i.e.
seo-forum-seo-luntan.com) is already old,, trusted and worked well, but today we got this error:
Table 'um_search_engine_optimization/search_engine_optimizationsessions' is marked as crashed and should be repaired
The
Cpanel was working, so there was way to fix it.
Thanks to this
http://php.about.com/od/mysqladministration/qt/repair_mysql.htm I repaired it.
Follow carefully (if you have this problem) these 4 steps. It's easy and it's amazing to have a working forum again!
I wish we never have
table/tables marked as crashed and should be repaired, because it's a kind of stressful, inconvenient for our visitors and friends, and it's not good to lose traffic to the forum at all.
Have a nice time!
P.S. After this we got another problem:
Database Error
Table '_search_engine_optimization/search_engine_optimizationlog_online' is marked as crashed and should be repaired
File: /home3/seoforum/public_html/Sources/Subs.php

Note: It appears that your database may require an upgrade. Your forum's files are currently at version SMF 1.1.19, while your database is at version 1.1.12. The above error might possibly go away if you execute the latest version of upgrade.php.
And I repaired it in the same way (the way mentioned above).
