** POST NOTE: Found the bug, my php.ini was buggy, replaced one with distribution works **

I was happily using Slackware v10.0 (kernel 2.4.26) with squirrelmail 1.4.3a for a while. When I upgrade to v10.1 (kernel v2.4.29) with squirrelmail 1.4.4, the error starts coming up.

I have searched the net and did not find any cases close to this.
I am not even sure where to start to look for.

Program: phpMyAdmin 2.6.0-pl3 (with mysql-4.0.23a)
ERROR: Missing parameter: Array

Program: SquirrelMail 1.4.4
ERROR : Could not complete request.
Query: SUBSCRIBE "Array"
Reason Given: SUBSCRIBE failed: Already subscribed to mailbox Array

Scenario: (besides the above error)
- Email works fine, SMTP and POP
- MySQL works fine, command line and via current web applications
- Apache Server/Website also works fine

Can some expert guide me where should I start to check?

Thanks in advance.

I'm assuming this means your all sorted out.

If not post back we'll try and help, if so, this post will take the thread off of the zero replies list.
