[Plugin: WP Photo Album Plus] Unable to create albums or upload photos

So I was able to successfully install and work with this plugin on my own WordPress installation no problem — does exactly what we’re looking to do! However, when I went and installed it on the company site, it does not allow us to add an album. I plug in the info and hit the button to add it, it takes a second and acts like it’s adding the album, but then the page refreshes and there’s no album there (no error messages either). Furthermore, there’s no wppa folder created under the wp-content folder (the plugin DOES create the wppa_album and wppa_photos tables in the database). I can manually create the a test entry in the wppa_album table on the database, which shows up in the wppa+ album page fine, so it appears that wppa+ isn’t having trouble reading. I’ve checked the permissions on the wp-content folder to verify 755, and we don’t have a problem uploading to the WP media library. Am I missing something? As a side note, we are using an https plugin (WordPress HTTPS) on our page, so I’ve posted there as well to see if that could be having any effect. Thanks!
