What does this database error mean.

I got this in my email about 4 of them mailed to me from my website:

Database error in vBulletin 3.8.4:

Invalid SQL:

And recently my forums keep going back in forth in time. It's like everything I did disappears (threads, any changes, etc.) and then comes back randomly, but mostly is gone

.

And most of my katz traffic is showing up error pages because the threads I submitted yesterday don't exist no more .

It's suppose to show 290 threads and 9 members but it only shows 22 threads and 7 members and it switches back in forth .

whos your host

Hi this error is coming from your hosting provider where it states this

MySQL Error : Can't create/write to file '/tmp/#sql_7a78_0.MYI' (Errcode: 28)

does not have proper chmod in that folder so it cant do anything you will need to contact your host and get them to fix this this is a very easy fix

Sounds like there is not enough space on the partition you are hosted on.

Ask your host to increase /tmp, 1gb should do

First, Make sure MySQL/Apache/
service httpd stop; service mysql stop

cd /var
dd if=/dev/zero of=tmpMnt bs=1024 count=1000000
mke2fs /var/tmpMnt
cd /
cp -R /tmp /tmp_old
mount -o loop,noexec,nosuid,rw /var/tmpMnt /tmp
chmod 0777 /tmp
cp -R /tmp_old/* /tmp/
rm -rf /tmp_old

Then add the entrys into fstab
nano -w /etc/fstab

add:
/var/tmpMnt             /tmp                    ext2    loop,noexec,nosuid,rw  0 0

restart apache/mysql
service mysql start; service apache start

(give this to your host)
(if you rip this gimme credit!)
