Hi Juan, thanks for getting in touch!
We’d be happy to help — but first, will you please confirm that you have a license for one of our premium products? And, if you have one, will you please log in so we can move this thread to our support forum? We use this Pre-Sales forum to answer questions about purchasing our plugins.
If you do not have a license, you are definitely welcome to post a thread to our WordPress.org forum, where we do a support pass each week.
In the meantime, I would suggest following the steps in this guide as a starting point. It will help check for conflicts with the active theme and other installed plugins and, if any conflicts exist, where they are.
Thanks so much!
Geoff
