Searching tickets is still much improved; however searching users is broken. This makes it very difficult to create new tickets, since we cannot pick a user from the search box, and if we try and add the user, they already exist. We're left with going to the users page which we cannot search, and clicking through page by page until we find them, and selecting the user and opening a ticket for them.
Of note, the prefix_user__cdata table is empty. Could that be the issue? Also, the prefix__search table does not contain any email addresses or customer names. I am running cron.php via /etc/cron.d/ every 2 minutes.
