admincp: user search does not work

[Peter Ostry]

vBulletin 3.7.5
The user search in admincp does not seem to work. A result is very seldom. Most times I get just a "no match". This happens with string parts and with exact matches. I've tried usernames and email addresses, parts and complete. I can find the users directly in the MySQL database but not via the admincp.

Edit: Sorry, I think I am in the wrong forum.
Feel free to move my post to the general discussions.

Try disabling your modifications and see if this fixes the issue.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Do you also get no matches when using the exact username and exact case?

[Peter Ostry]

Correct. I find very few users, exact match or not. I found some email addresses with only a partial string and I found an IP number. We have two products installed: "MODx integration" an "Nested Quotes". As plugin the "ad-after-first-post" thing. I find all user information in MySQL. eAccelerator is activated in PHP, if anything of that rings a bell.

You can try disabling plugins to see if that makes a difference.

Otherwise please post a screenshot (phpMyAdmin?) of the columns in your user table.

Doesn't make a difference. Some users are found and most not.

Screenshot? hmm ... quite big.
Are there specific columns I should look for? Don't see much difference between a found and a not-found user.
