--------------------------------------- ! WARNING ! ---------------------------------------
You're using PHP 8.0 with JIT enabled. This provides significant performance improvements.
HOWEVER, it is EXPERIMENTAL, and has already been seen to cause weird and unexpected bugs.
Proceed with caution.
If you want to report any bugs, make sure to mention that you are using PHP 8.0 with JIT.
To turn off JIT, change `opcache.jit` to `0` in your php.ini file.
