Update to wrong DB
 

Hi,

I have two forums vBulletin 3.7.3 as main forum and Vb 4.1.3 for testing purpose.

Of course both forum's have different database.

Yesterday I planned a upgrade for the testing forum software from 4.1.3 to 4.1.6 but by mistake I set the wrong db in the config file. (the one for the main forum)

the upgrade for 4.1.6 didn't complete and the the main forum is now useless I get only db error's. :eek:

Is there a way to revert this?
Unfortunately there is no (recent) back-up

Every help is welcome.

Regards,

Your going to have a very hard time fixing it.

Can you get to the admincp and go to the optimization/repair then use mysql schema option at the bottom try repair the database. I recomend backing it up first incase that does worse and someone else finds a fix.

You might also want to look at backing it up atleast once a week if not once a day!

Can you post here what db errors are you getting?

I see that all errors are from the test forum only, I fix this already by upgrade to the right DB.

The main forum DB does not create anything the screen stay blank.

I cant go to the admincp after login the screen stay blank.

The VBadvanced does load but when I follow a thread I get this;

Warning: Invalid argument supplied for foreach() in [path]/includes/functions_editor.php on line 93
Warning: Invalid argument supplied for foreach() in [path]/includes/functions_editor.php on line 93

I try to fix the main forum with upgrade but that didn't work either.

Then I get this

It is not possible to upgrade directly from vBulletin 2 to vBulletin versions 3.7.x and newer due to incompatabilities in data structures.

If you are currently running vBulletin 2 and would like to upgrade to the latest version of vBulletin, please begin by downloading a version of vBulletin 3.6 from the vBulletin Members' Area.

But if you don't have a backup, there really isn't much you can do. Could you just bite the bullet and upgrade to 4.x fully?

The latest backup I have is from 1 September - I can live with that.
Upgrading fully to 4.16 is a lot of work and I have far to little time to rebuild the lay-out and all the hacks.

It was a good lesson for backing up every time. :)

Thank you all for the fast respond.
