I am trying to add a theme to a form and the theme saves but after exiting it does not show up

When I go to themes I selected the theme I want it adds it, than i save it and get the green check mark. After exiting out however it does not show the theme. I have tried using different browsers which also did not fix the problem. Thanks in advance.

Can you try to clear your form cache and browser cache - How-to-Clear-your-Form-Cache.

If that does not solves the problem, please let us know the theme you are trying to add, the form,  and we will look into this.

I cleared the cache and it still is not working. The name of the theme I am trying to use is called "Testing"

I have checked from Theme Store and actually found more than one 'testing' Themes.

Also, these Themes as their name says, they are 'testing Themes', which mean they might not fully work on every form as they should. 

Let us know which one you are using and we will check what the problem is.
