I recently switched from the 2013 theme to Customizr. My website now has a huge problem that I haven't been able to fix. If you click anywhere besides on a link, the site turns grey like it is loading another page, and then it locks up. It can be fixed if you refresh the page, but it looks very unprofessional. In addition, it is about twice as slow as when I was using 2013. How do I fix these issues?
