- Clear the cache and run cron. This will fix 90% of the problems you encounter (if you're curious about what cron does, see this: http://kerasai.com/blog/2013/11/21/what-exactly-happens-when-drupal-cron...).
- Does the site sometimes disappear and/or look different? Probable cause: The two webservers aren't identical. Solution: Ask Contigex to investigate.
- Does running drush on the server give you weird path errors? Probable cause: Modules have been moved. Solution: Rebuild the file registry table using the "drush rr" command.
- Sometimes "drush cc all" and "drush rr" do not fix the problem. This is because they don't actually clear every cache table in the database. Solution: Log into the site database ("drush sqlc") and truncate the "cache_bootstrap", "cache_path", "cache_features", and "ctools_object_cache" tables.
- Is the user having login problems? Probable causes include:
- They were created as a Drupal user instead of a CAS user.
- They are using their entire email address as their login instead of their CAS ID.
- They are using an outside email address as their login ID.
- Solution: If possible, correct the CAS user entry or create a correct CAS user entry. If they continue to have problems, delete them and recreate their login.
- Is the user not allowed to edit a page? Things to check:
- Does their role allow them to edit (e.g. Content Editor)?
- Is that role allowed to use Full HTML?
- Is the page unpublished, and authored by another user?
- Problems with the file manager
- Can't see toolbar buttons? Probable cause: The site is using the wrong jQuery version. Solution: Downgrade to jQuery 1.7 using JQuery Update.
- Can't browse the file tree? Probable cause: The directory owner and/or permissions are wrong. Solution: Petition your friendly neighborhood sysadmin to change the file owners and/or permissions so that the webserver can read and write files.
- Can't delete file? Probable cause: The file is still in use on a page or on an old revision of a page. Solution: Remove the file from the page, and delete old revisions that reference it.
- Admin toolbar is missing? Solution: Revert the Admin Toolbar feature(s).
