Hi there,

Thanks for contacting us. Sorry for the inconvenience. Please downgrade PHP version 8 to 7.4 & check again.

we support only PHP 7.x and PHP 8.0.x, not PHP 8.1

Besides error message can be from different extensions as well, not only from ours.

Hi, I have the same problem with Themis template.
When I login via front-end, with php 7.4 it works, with php 8.0 there is 0 error
in_array(): Argument #2 ($haystack) must be of type array, null given.

Now we are back to php 7.4, but we need to update it soon.

This is the link of the page that generates the error once you try to login.
With php 7.4 everything works correctly
