Add new page – no option for parent under page attributes

This plugin causes the ‘parent’ option to disappear when adding a new page in WordPress v5.

Sounds like other plugins cause this issue too:

“When adding a new page I looked for where I was supposed to set parent page and could not find it – used google and came across a thread mentioning where someone had said it was found under page attributes, with a screenshot. The option does not appear in my page attributes – the only option is order.”
