MyBB Community Forums

i wanted to upgrade from 1.2 to 1.2.1
i close the forum
while upgrading i dont deactivated plugins (nothing about this in http://wiki.mybboard.com/index.php/Upgrading ), following error appears:

mySQL error: 1194
Table 'mybb_datacache' is marked as crashed and should be repaired
Query: SELECT title,cache FROM mybb_datacache

i tryed to move to my old version (from www & sql backup) ,but error is the same

how could i fix it ?

please help

Using PhpMyAdmin, run the following query:

REPAIR TABLE mybb_datacache;

it works.
i recovered and succesfully upgraded to 1.2.1

thank you very much
