Can’t customize my site if I’m using your theme– if I click the customize button the left-hand sidebar pops up with a note that I’m customizing my website, but there is nothing else. The default WordPress themes work fine this way.
Problem may stem from the fact that I started work on the site before the domain name propagated, so I was using an address composed of its ip address plus the /~cpanel username. I had this problem before with an earlier site but changing the URL in the WordPress settings section fixed it.
I added the code in the article to increase the memory but no change. I have several other sites with this theme but don’t have this problem. I’m going to use another theme, not because I don’t like yours but because it suits this client more, but I’ll reinstall your theme and see if that helps
