Error message when trying to load a page

Hello, 

I'm getting this error message when following a link within my Process Wire website, I wish I had more information but this just suddenly started happening:

Umm… Fatal Error: Uncaught TypeError: PageFrontEdit::inlineSupported(): Argument #1 ($field) must be of type Field, null given, called in wire/modules/Page/PageFrontEdit/PageFrontEdit.module on line 588 and defined in wire/modules/Page/PageFrontEdit/PageFrontEdit.module:291

Any help or advice would be very helpfull,

Could you check if there is a field that no longer exists in the backend but is being indicated as editable in the FrontendEdit?? Like, say you deleted 'text' field and now you are trying to call 

<edit field="text"></edit>

At least this is what I get from reading the source of PageFrontEdit.module, but I don't use this module much.
