Hello and thank you for contacting the Toolset support.

It seems that the first three notices are triggered by a wrong use of WordPress functions(is_archive, is_home, is_search) in the theme's file. I am sure they won't appear if you switched to a default theme such as Twenty-Twenty.

The other warnings are probably caused by the logging of the previous notices.

These messages appear on the WPForms page, right? Please check if they will disappear if you temporarily deactivated Toolset plugins.
