Hi,
I’m glad it works now. I understand if you are frustrated, but I am here to help you out. Unfortunately we don’t have the capacity for live support though.
I suggest checking the documentation step-by-step, it explains all the things you need to be aware of initially:
– Getting started
– If you had the lite version, you can import the options from the lite version as well
From there, I suggest checking the:
– General Options and all subchapters
– You can also check the behavior options, and what are they for
To replace the theme search, try the automatic theme search replacement tool:
– Replacing the theme search bar
If works for most themes, that use the get_search_form() method, that is recommended by core WP development guidelines.
