NEWBIE IP Confusion

You called it… I deleted the “A” record and it started giving 504 Errors and timing out on the blog section of my site. That’s the only word press section of the site.
I added that record back in and it works again. Not a sub domain though. It’s just Marci Curtis - Detroit Wedding Blog. Even that would sometimes come up, but you couldn’t click around or get into the back end of it.
Any suggestions? Does keeping the gray “DNS ONLY” identical cloud hurt me in any way? Originally I believe support said it would keep me from enjoying all the benefits of Cloudflare. Sounded a bit dramatic :slight_smile:
Again, THANK YOU!
