Am I doing something wrong?
Here's the setup:
PHP 4.3.9
MySQL 4.0.18
Windows 2003 Web Edition
IIS 6

I'm having a bunch of weird problems
1. Even though I installed XOOPS 2.1.1, the version in the footer reads 2.1.0
2. Can't send lost passwords, as the system claims it can't find a valid matching email
3. Test user can't delete own account even though option is checked

The last time I played with XOOPS was 2.0.9.2 on the same setup as above (php was 4.3.5, though), and I don't remember having this much trouble with such simple items.

Also, user administration is painfully clunky, as it takes me five or six clicks just to get to where I can edit a user's information. Is there a better user admin module out there?

For starters, XOOPS 2.1.1 is a developer version (beta) and there may be bugs. The development is progressing quickly, you can test the nightly builds, but this version is not for a production site.

For production sites use 2.0.10 stable.

HTH.
