This is the finer detail I can get with the error when debugging on the OS side.

I finally managed to get IPS working with PHP8, there were a lot of PHP8 extensions missing to enable. This link came to me to see the extensions and I visualized that several were missing. In practice, I enabled the same ones in PHP7.4 with their equivalent in PHP8.0.

That’s was going to be my next suggestion… to run the IPS compatibility checker to see if you were missing a PHP module.  Glad you got it squared away.  🙂

For anyone else reading this, any time you upgrade/change PHP and encounter an error, it is advised to double check the compatibility tester:

In your case there, it was the mb_string php extension

And a lot more that were missing for PHP8.

At least you got it squared away. People think PHP is this single static package and that it’s easy to install/manage it. There are lots of moving parts for it that have to be accounted for!  🙂
