Locating signatures

[Shin2k35]

For some reason signatures don't work on my board. I have tried going into vb3_user and manualy placing a row for signatures, as I've seen in past installations and versions. I then edited my account through myphpadmin and gave myself a signature. Nothing showed up on the forums and doing this errored the admin user search function. So I've deleted that row. Then I went into my profile and edited my signature. Now I'm the only person on the forums with a working sig.

I can't seem to grasp it :( I'm running vB 3.5.4. Does anyone know how to fix this without destroying everything?

Have you recently upgraded, moved to vBulletin from another software, or made any other significant changes to your site?

Are signatures enabled for the user groups in the usergroup manager?

Have you ran Maintenance > Update Counters > Fix Broken User Profiles?
