Issue with links not working

Hi
I have GeoDirectory installed with the following GD plugins:

• GeoDirectory Advanced Search Filters
• GeoDirectory Location manager.

When I search for places nearby, I get the locations nearby as I would expect, but when I click on the link I get an error:

OOPS! THAT PAGE CAN’T BE FOUND.
It looks like nothing was found at this location. Maybe try a search?

I have tried what’s on this post:

https://wpgeodirectory.com/support/topic/gd-listings-links-not-working/page/2/
But it still doesn’t want to play.
I have disabled all none GD plugins, but I still get the same error.
It was working fine, but for some reason it’s just stopped working.
If I set the permalinks to plain, the links work, but the what’s nearby doesn’t.
Any help is appreciated.
