Hello there! A few weeks ago, in order to customize my DNS records, I was told that I needed to host my DNS to a 3rd party provider such as CloudFlare because my provider does not accept custom DNS records (required for my Mailgun account). Everything seemed to be working fine until I brought X Theme into the mix two days ago (which I know that I will love if only I can get past this issue). Anyway, I began work on my site, every 10 minutes or so, an error message pops up that says something went wrong in the front end, causing any progress I made to go unsaved. The page then displays the 521 error message shown here: https://support.cloudflare.com/hc/en-us/articles/200171916-Error-521-Web-server-is-down. It was suggested to me that I disable SSL and see if it helps, but it only made things worse, as now my site seems to have lost all of its formatting. I then re-enabled the SSL option in Cloudflare, thinking that would at least correct the formatting issue, but it did not. I then uninstalled and reinstalled X Theme, but the formatting is still very, very wrong. I read a post about Cornerstone issues with Cloudflare here: https://xthemeusers.com/tutorial/fixing-cornerstone-cloudflare-related-issues/. I also see quite a few similar posts in this support forum, but the truth is, if you haven’t already figured out, I am very tech-challenged 
and therefore not confident that I can troubleshoot this without making matters worse. What can I do?! Any help you could provide would be greatly appreciated. Thank you for your time. Sincerely, Marissa
