New code has been added to BPS Pro 9.0 and a new BPS Pro 9.0 zip file has been uploaded at 6-25-2014 2:02 PM PDT.
Impact: Very few people have been affected by this problem overall. Somewhere in the neighborhood of 1 out of 1,000 people, but even 1 person is 1 too many.
Diagnosis of the problem: BPS Pro was previously turning off AutoRestore during BPS Pro upgrades, but it appears that if anything at all interfered with the BPS Pro upgrade process and caused even a slight delay in the BPS Pro automated upgrade process, then AutoRestore was not being shutdown in time and the result is that all plugin files were being sent to Quarantine.
Solution: The new BPS Pro 9.0 code contains an additional AutoRestore FailSafe Shutdown to ensure that all BPS Pro automated upgrade steps have been completed before the AutoRestore Cron will be allowed to run again. The ARQ Cron will not run unless all BPS Pro automated upgrade steps have been completed by BPS Pro. This is very similar to the code that is used for ARQ Automation during WordPress Automatic updates, which works flawlessly without any problems.
Additional Benefit: ARQ no longer needs to be shutdown either automatically by BPS Pro during an upgrade or manually by someone since the ARQ Cron is not allowed to run until all BPS Pro automated upgrade steps are completed by BPS Pro.
Error Messaging: Most likely no one will ever see this error message below, but in the event that a BPS Pro upgrade does not complete successfully then the ARQ Cron FailSafe Shutdown Notice will remain permanently and the ARQ Cron will not run until whatever is causing the BPS Pro upgrade to fail is fixed. ie deactivating a plugin that is preventing the BPS Pro upgrade from completing successfully, file or folder permissions, file or folder Ownership problem, copy or write problem, etc.
