 * Hi Helmut.
 * Running into a small issue. When using CLI, I am getting a fatal error triggered
   coming from the bootstrap code.
 * `PHP Fatal error: Uncaught TypeError: array merge(): Argument #1 must be of type
   array`
 * I think the `array_merge()` function is failing because it’s receiving `null`
   values from the `update_plugins` transient. I have not modified the bootstrap
   code at all; this error was found by my hosting provider (Cloudways) when they
   were troubleshooting an integration issue (Cloudflare Enterprise).
 * Hoping you can take a look at this and let me know if anything can be done.
 * Thank you!

 * Hi!
 * Thank you for your bug report. I have just released an update that provides a
   new Bootstrap code (basicV2). Please use this new Bootstrap code for your plugins
   from now on. I apologize for any inconvenience. By the way, the new Bootstrap
   code now also supports multisite installations 😉
 * Best regards!

 * That’s awesome! Thank you so much for the quick turnaround. I was noticing that
   the multisite installation started working, so I figured you had worked on that
   so THANK YOU for that as well.
 * Appreciate your work on this so so much! 🙂
