Hello @cachencho,
The issue regarding the error has already been fixed. So please update to the recent version of the WP Travel plugin and verify the issue.
As for the testimonial option, when we tested the theme, the option is working fine as you can see in the screenshot below:

So make sure you have disabled the option properly and save.
Hope this helps.
If you have any issues further then kindly let us know.
