Server Error Mysqli prepare error: Key 'last_post_date' doesn't exist in table 'thread

Sort by date Sort by votes
Typically this indicates a corrupt backup (or restore), which is typical when using phpMyAdmin.

Can you run the following command and post the full output:
Code: 
SHOW CREATE TABLE xf_thread;

Unfortunately, your backup would appear to be corrupt or incomplete. It's missing all of the indexes on that table, including the primary key. Determining the differences across the database may be very difficult, particularly if you have add-ons installed.

You don't have any other backup?

:eek: That's a lot of data gone oh no :s I tried 3 backups all within 3 days time, strange all got corrupted.

I tried those SQL backups but I have /var/www/ backed up too but doubt that will fix anything?

How many add-ons do you have installed? What sort of add-ons are they?

Can you show the first CREATE TABLE line in your backup's SQL?

One of the big weaknesses in using a PhpMyAdmin export as a backup (which is what I assume you did). Invariably if the DB is large the export times out and you end up with a "shortened" export that does not contain all the data.
The same can happen on an import of a large DB.

That would suggest an issue with the restore process.

Again, if using phpMyAdmin, that's not uncommon.

Thank you very much guys! I'm sorry for the confusion. To prevent further issues what's the best recommended way to take backups?

I use SSH.
You will invariably require root access for that.

Dump:
Rich (BB code): 
mysqldump -udatabase_user -p --single-transaction --skip-lock-tables database_name > /path/to/backup/database_name_$(date +%d.%m.%y).sql


Zip:
Rich (BB code): 
tar -czf database_name_$(date +%d.%m.%y).tar.gz /path/to/backup/database_name_$(date +%d.%m.%y).sql


Restore:
Rich (BB code): 
mysql -udatabase_user -p database_name < backup.sql

Depends on if you are on a VPS/dedi or a shared host. If VPS/dedi then using mysqldump is pretty much standard and works well to export the DB via a CRON script.
If you are on a shared hosting and they allow the PHP exec() function then this may work: https://xenforo.com/community/resources/solidmean-forumbackup.3605/
Otherwise, you can try increasing the time-out limit in your php.ini (your shared hosting provider should be able to provide you instructions on how).
