So had a client contact me that at 7pm or shortly after they messed up their skin and requested it be restored from our hourly backup. So we dropped the database and restored it from the 6:02pm database backup. All posts after 6pm are gone, so the restore went fine, but client says his theme still has the changes after 7pm. Any idea what is causing that?
They would need to have caching implemented to store templates as files, hence my first question.
For performance reasons, you may choose to have the public-facing side of XenForo load its templates from files rather than the database. Note that in order for this to be of benefit, you must have an opcode cache installed on your server (APC, eAccelerator, XCache etc.)
