Uncaught Error: Call to a member function set_custom_path()&set()

Hi @ccstring,

The error seems to be originating from Siteguard plugin. Please try deactivating the plugin and check if the error is gone. I would recommend you to also switch to one of the default themes like Twenty Twenty-One and then perform the error test.

If the error is gone after you deactivate the plugin, please reach out to the plugin support for help with the error.

I hope this helps!
