I am having this same issue! I had the Coming Soon mode enabled while I built the site, and now the customer wants it live TODAY and I can’t get it to go live!
I disabled Coming Soon and disabled the plugin, and it still shows the Coming Soon page I built. I DELETED the plugin, and it STILL shows the Coming Soon page, with the same graphics, but styling removed! I reinstalled but did not activate the plugin, and now the styling is restored, but the site at https://viol.us/ is STILL SHOWING IN COMING SOON MODE in all browsers–Firefox Private window, Chrome Incognito, Brave private page, Safari, and Edge. How can I get the site to show up? Help! I didn’t think there would a caching issue with incognito/private pages, but it is not showing the site.
I have deleted all caching plugins from the site. I have looked for a maintenance file in File manager and there is none. I tried changing the wp-installing from true to false (per this article: https://www.seedprod.com/wordpress-stuck-in-maintenance-mode/) and that did nothing.
I really don’t know what to do. I spent a couple weeks on this site and I’m afraid that all my work is for naught!
