Hello,
We are facing issue “The preview HTML did not include a closing html tag. It may fail to load or work properly” on editing Sabai directory page details=SandboxUrl[/details]. This page is selected as sabai directory plugin’s listing page. When I try to edit that page you can check in screenshot the issue we are facing. I have added the console error as well within screenshot.

For fixing jQuery is not defined issue I tried adding js within sabai plugin files but still page was not editable. We use “Breeze – WordPress Cache Plugin” cache plugin so tried disabling same but still facing same issue. When I disabled the sabai plugin then the page was editable but we can’t disable it. So please provide your suggestion’s on fixing above issue. Also I tried the solutions provided on other threads it didn’t fixed my problem.
Thanks!
