Hi, I don't understand.
I have a .com site and a .net site each are on two different hosts (long story why, don't ask LOL!)
Anyhow, when I go to customize, one gives me more options than the other.
Normally it will prompt you to install a styles plug in. I made sure to have the same plug ins incase it was for this one that I have on my .com site. But still gives me limited access to customize. I have all same plugs ins to in other words. See photo. I inserted the html code for the photo and a link if the html code don't show photo.
