 * I just updated the plugin to 1.6.1 and it “crashed” my site. I used recover mode
   to disable the plugin. I am running WP 6.8.2, Server architecture: Linux 6.1.0-
   38-amd64 x86_64, Web server: Apache/2.4.62 (Debian), PHP version: 8.2.29 (Supports
   64bit values). WooCommerce 10.1.2.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fbroken-plugin-fatal-php-error%2Fpage%2F2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello
 * Firstly, many many thanks to [@robertpheller](https://wordpress.org/support/users/robertpheller/)
   for raising this issue and for chasing up on it. I encountered the same problem
   around the same time. I have been following this thread for updates almost daily
   for the last half year or so.
 * Using the listed replacement file fixed my issue, but the BackWPup plugin incompatibility
   has now resurfaced with the new file (PayPal Zettle POS (version 1.6.2-izet-523-
   2)).
   I only noticed that the POS plugin had deactivated when I realised that 
   my stock counts were entirely out of whack, forcing a full inventory.
 * I specifically created this forum account to echo Robert’s interest in a scheduled
   update that will allow me to return to the standard plugin with automatic updates
   that will hopefully prevent unexpected downtime or stock desynchronisation.
 * Thank you both for your work on this.

 * I recently deleted the BackWPup plugin because it was insisting on backing up
   the whole site (DB AND files), and would not just backup the DB. (I have a separate
   process for backing up the files.) This eventually resulted in filling up my 
   disk and causing all sorts of problems. (I eded up writing a bash script to replace
   the BackWPup plugin.) And I too am awaiting putting the Zettle plugin back on
   automatic updates…
