I do like to get Vantage in a knot :)
My free listing package still shows the user the option to have featured listings. I didn't want that and could see that there was no facility to turn it off so thinking outside the box thought not a problem I'll make them part of the plan but I'll put -1 days in so they don't get featured listings and can't select featured listings - Simples.
Mr Appthemes I have broke it
This did several things
It turned off the feature on all my payment packages
It placed the listing in featured on both front page and category
It placed another ad placed at the same time into featured
I couldn't get the ads to cancel from featured
I couldn't get rid of the -1
I now have no featured facility - I think I might have to pay a visit to the database
The moto of the story is don't try and be a smart arse
