BPS Pro is a very advanced plugin that has built-in troubleshooting – all BPS Pro features can be turned On or Off to isolate exactly which BPS Pro is causing an issue or problem or to eliminate that BPS Pro is causing an issue or problem. Activating or deactivating the BPS Pro plugin does not do anything besides deactivating/activating BPS Pro (deactivating/activating BPS Pro does deactivate/turn off AutoRestore/Quarantine, but that is not relevant to this issue).
