I currently have a members only wordpress site. I use s2Member for the restrictions to ensure everyone has to log in. It's just a small site for a group with a handful of members. Each member is able to edit certain pages within the site, but only the admin login is capable of editing everything on the site. I restrict who can edit what with the role scoper plugin. Everything worked great at first. Members were able to edit their specific pages and upload pictures. A few days ago, however, all the accounts other than the admin login were no longer able to upload pictures. The editors can still edit text on pages, but when they click the upload/insert button (or go to the media library), a box like the "add media" box pops up, but instead of being able to upload pictures it's the website's login welcome page (the page members see upon first signing in). That's now happening for every account and I'm running out of things to try to correct this.
Version is 3.3.2
Using a twentyeleven child theme.
Some help would be greatly appreciated!
