Suddenly getting an error.

[Emufarmers]

Sounds like a corrupted database table. To see which table, add

$wgShowSQLErrors = true;

to the bottom of LocalSettings.php (remove the line once you've fixed the problem).

Repair the damaged table with phpMyAdmin or the database management tool of your choice.

Ok so repairing the SQL database did not seem to work. I got many messages saying "Table does not support repair."

Once I enable the:
$wgShowSQLErrors = true;

I get the following message:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
DELETE FROM `objectcache` WHERE keyname='redhaxn_redhaxcache:idhash:1-0!1!0!!en!2!edit=0'
from within function "MediaWikiBagOStuff::_doquery". MySQL returned error "1030: Got error -1 from storage engine (localhost)".

Do I need to upgrade mediawiki, do you think that will help?

I get the same error from the installation script when I try install another wiki on the same database.

Here is the output:

Ok so repairing the SQL database did not seem to work. I got many messages saying "Table does not support repair."

I believe you have to actually tell your tool which table to repair (objectcache).

Do I need to upgrade mediawiki, do you think that will help?

You haven't indicated what version you're running now, so I can't say for certain, but it could help (and certainly won't hurt).

I get the same error from the installation script when I try install another wiki on the same database.

You haven't actually installed a separate wiki; you're just re-running the installer. For a separate installation, you need to use a separate database or prefix.

A couple more thoughts: Make sure your database user has all privileges for the database (including ALTER and DELETE). Also, make sure the MySQL server's disk isn't full. (If you're on shared hosting, you may have to ask your host to verify this for you.)

I can't figure it out.

Any idea how to salvage the wiki and rebuild it??
