@ Steve – What version of BPS Pro do you have installed? Which version of WordPress do you have installed? How exactly did you update the plugin? On the WordPress Plugins page > update now link, on the WordPress Updates page > Update Plugins button…? Was AutoRestore turned On or Off before you updated the plugin?
So far we have one potential problem issue with the new ARQ Automation code for WP Shiny Updates and WP Automatic Updates, which is this scenario: Someone has ARQ turned Off and updates a plugin. Currently in BPS Pro 12.2 ARQ will turn itself back On automatically after doing any plugin file backups that are necessary. So we are changing that in BPS Pro 12.3 by adding another checking condition that checks the status of ARQ before the plugin update occurs and if ARQ was Off before updating a plugin then ARQ will still do any necessary file backups, but ARQ will NOT automatically be turned back On. The reason for that is if someone has manually updated WP Core files and left ARQ turned Off then ARQ should not be turned back On because WP Core files will be quarantined since WP Core files were not backed up yet. WP Core file backup is not processed by ARQ Automation code for plugin or theme Shiny Updates, unless WP Core and Plugins are being automatically updated at the same time by WP Automatic Updates.
