I wonder if the theme is compatible with PHP8.1?
I have upgraded a website and I get “internal server error” in the cart.
I am using the latest version of Woodmart, wordpress and plugins.
The website is up and running so I would rather not deactive all plugins. But I have checked with one of the plugins that I suspect could be the problem.
I will come back if it does not solve.
But, as far as you know, your theme should be compatible with PHP8.1?
