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?
