This morning we updated our aMember Pro to 4.5.1 from 4.4.4. After the update was completed, we had major problems. No admin access. No membership access. No new memberships, etc. A completely crashed membership system. Sent in support ticket but received no reply. We did a backup before we updated, but when trying to upload the backup, we encountered server problem and the upload quit. We've been trying to correct the problem but to no avail so far. Question: Which files should we be manually uploading to revert back to our working copy, and which files should we not touch? Any help is appreciated.
