Registration issue
 

When someone goes through the registration process, after step 2 of 2 where you pick your user name etc and click "Complete Registration" i get the following message:

Database error
The Forums database has encountered a problem.
Please try the following:
Load the page again by clicking the Refresh button in your web browser.
Open the <site> home page, then try to open another page.
Click the Back button to try another link.
The <site> forum technical staff have been notified of the error, though you may contact them if the problem persists.

We apologise for any inconvenience.

And the User ID's are actually created. The thing is with the message above, most people will think the process failed plus it looks unprofessional.

Any idea how to fix this? I don't know if the anti-spammer measures posted here in this forum are behind the problem.

need to error in full.

Yes the full error from your server error logs would help.
What version of vB4 are you running?
What PHP version are you running?

But we can see if this is from a mod, by doing the following.

Open your includes/config.php file and below<?php add this line:

So it looks like this:
Then try and register and see what happens.

I haven't made the changes you mentioned ozzy as i thought i would post the error first. I'm a total newbie at this stuff and want to avoid creating more problems.

I went and set up the error reporting thing (told you i was a newbie!) and recreated the problem. This is what i was emailed. I removed my IP and site address, but everything else is everything i got sent to me:

Database error in vBulletin 4.2.2:

That error is most commonly caused by plugins or addons that incorrectly set auto increment fields within vBulletin.

I would suggest reading this, https://www.vbulletin.com/docs/html/...l_duplicatekey

Specifically the query starting as:

I can't seem to run any queries. I adjusted the config file as follows:

// ****** USERS WITH QUERY RUNNING PERMISSIONS ******
// The users specified here will be allowed to run queries from the control panel.
// See the above entries for more information on the format.
// Please note that the ability to run queries is quite powerful. You may wish
// to remove all user IDs from this list for security reasons.
$config['SpecialUsers']['canrunqueries'] = '<myuserid>';

But every time i go to maintenance>Execute SQL Query i get this:

You are not authorized to execute SQL queries

If your userid is 1, then that line would read as:

Is that what you have?

Thanks, that worked. I had the ID name there.

Am i suppose to run them all, because the one line you mentioned didn't work. I copied and pasted the line as follows:

ALTER TABLE `user` CHANGE `userid` `userid` INT( 10 ) UNSIGNED NOT NULL AUTO_INCREMENT;

And when i ran it, i got the screen attached.

ok, i ran all of them and got the following message (screenshot attached).

Any idea how to fix the problem?
