Problem:

I am using the cred_form_validate hook to force mandatory taxonomy fields.

Solution:

All pages content templates field is set to templates dynamically assigned by toolset.

is there a way to put it on none for all the pages ?

Solution:

You can try these:

Dashboard-> Toolset-> Content Templates, in column "Used On", find that content template which is assigned to post type "Page", remove it(or resign it from post type "Page"), and test again.

Problem:

The issue here is that the user wanted to know if it was possible to take payments using our Toolset Forms plugin without having to install a 3rd party plugin.

Solution:
Unfortunately no you are not able to take payments using our Toolset Forms plugin without the assistance of a 3rd party plugin.

Currently the only plugin we have payment integration with is Woocommerce.
