Hi, it's my job!
Fixing this Popup issue on your Drupal site is pretty simple. I checked your site and there is problem with javascript which caused this error:
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience."
I can help you to fix it now. Please give me the details of this project to get started right away.
My bio: I'm a Drupal themer/developer, I have over 6 years working on various Drupal projects from (Design, HTML, CSS, Javascript) to development (PHP, MYSQL, Drupal). I can create new themes, fix theme issues and module issues, create and upgrade Drupal sites, also suggest the best solution for Drupal site owners.
Thanks,
Dang
