I just did an upgrade 1.5 from 1.3.8. I did a fresh install and tested before I did this, plus I tested the db and it seem to work fine, but when I put it in the root folder, and turned the ssl on, the admin does a loop. the first time I logged in, it worked fine, asked me to update my password. Now when the ssl is on, I get the loop of death it just keeps loading the log in page. When I turn off ssl in admin, it works fine.

This is not my first upgrade, but for the first time, I am stumped. I think it has something to do with the cache folder and old modules stored in the database. Does anyone have any ideas? I'm willing to try anything.

Thanks
