@imath That’s what I originally though. However, I have a different website with the same theme and that works perfectly fine.
It is worth mentioning that 2 of my sites with this issue (MovieFloss.com, BeerAlien.com) are in the same web hosting. The one without any issues is hasted thought Bluehost (sdmetal.com). Because of this, I think the issue might be Hosting related. Could that happen?
Everything was working on the 2 sites until BP 10. Thank you for all your help BTW.
