I have now found better alternative with more features that works better than WP Ghost and does not break anything!
After reading this post by @vandung93, I tend to belive that plugin is doing some funny business since I am facing a similar issue. I and my two devops spent a couple of days just to work out WP Ghost plugin but I’m now started to believe that the plugin has some bugs. Now, I’ve asked my dev to check ASAP WP Ghost plugin into a different hosting server, different domain & site running with one of the HMWP listed compatible theme. @petersquirrly perhaps, I’d appreciate you to provide me your convenent time (GMT-00, 10am to 8pm) to meet online with me and my dev and I’ll share my live admin account to you. I already have PRO subscription and I’d contacted you over support.
