Undefined Errors in a 8.5.2 site
Errors are: e.g
When I run either of the 'Index Search Engine' automated jobs - I get:
Trying to get property 'fsID' of non-object
When I try to add a page list to any page in the front-end - I get:
Exception Occurred: /***/concrete/blocks/page_list/controller.php:62 Undefined property: Concrete\Block\PageList\Controller::$orderBy (8)
When I try to amend a page list that has already been added to the front-end - I get:
Exception Occurred: /***/concrete/blocks/page_list/page_list_form.php:281 Undefined variable: isOtherPage (8)
If i try to add 'Page Title' block to front end - I get:
Exception Occurred: /****/concrete/blocks/page_title/controller.php:63 Undefined property: Concrete\Block\PageTitle\Controller::$useFilterTitle (8)
I'm running PHP v7.2.20 - I've tried switching it to 7.3 / 7.1 / 7.0 - all have the same issues.
I'm using a custom theme/block/templates, but I have switched back to Elemental, removed all custom block/templates, deleted Cache, etc, and that has no effect.
It's on a local dev server right now. I have tried moving it to another server with a completely different build, and the same errors are occurring, so it would appear to be site specific.
Can anyone help me out as to what might possibly cause these specific errors please?
Both servers I've tested on have quite a few other C5 installs running with no issues, various versions up to / including 8.5.1 - so I would expect that this site *should* work okay from a setup perspective... This is the only 8.5.2 site I currently have running, so I don't have others to compare it against.
