 * When I add a user (as author for example), it’s not possible to add or view the
   posts. The error is ‘session expired’.
 * As administrator there’s no problem.
 * I uninstalled the plugin and deleted it, then the problem was solved.

 * Hi, Simple Lightbox has been tested in many multi-user environments and no issues
   were found. What other plugins do you have installed?
 * The issue you’re reporting does appear to be caused by file permissions in some
   cases. You may want to check to make sure all WordPress directories and files
   have the proper permissions.
 * See WordPress’ official documentation: [Changing File Permissions](http://codex.wordpress.org/Changing_File_Permissions)
 * Once you’ve corrected the file permissions, I would recommend reinstalling Simple
   Lightbox. Your issue should be resolved.
 * If not, I would recommend [checking for conflicts with other plugins and themes](https://github.com/archetyped/simple-lightbox/wiki/Troubleshooting-Plugin-Conflicts).

 * Hello,
 * I’ve read the documentation about changing file permissions. Tough, nowhere I
   find a list what the permissions should be per file or directory.
    Since everything
   works fine now, I assume all the permissions are good enough (?).
 * You cannot test it with every plugin, I understand. So maybe it was a conflict.
   I have this plugins:
 * – addthis social bookmarking widget
    – fast secure contact form – google analytics
   for wp – google sitemap – nextgen gallery by photocrati – no page comment – responsvie
   lightbox (added after uninstall Simple Lightbox) – wordpress seo – yet another
   social media icon plugin (yasip).
 * rgds,
    Dirk
