Ok - so I've read a lot of the other login issues... and I think I may have a session problem. Since I'm a noob though, I don't really know wtf to do about it! I really want to use plogger over any of the other possibilities I have seen...
First I had the first time login issues many others did with repeatedly invalid logins using the provided password and username. So I went into myPHP admin stuff - changed the password and voila I could sign in! Yay!
Then when I actually try to do anything from there I get popped back to the login page. Over and over. Even after resets, checking my permissions (I allow everything from my site, etc.)....
(Just in case it's important I use ipowerweb for hosting & Dreamweaver for my site building - I uploaded using Dreamweaver.)
Yep, it's a sessions issue. Here's a link to the previous ipowerweb discussion. Also, the SVN code (latest code that is being developed) has a quick flag in the plog-config.php file that you can easily set up your session save path if you want to try that.
