Website urls in listings problem after update from 3 to 4
My old site is running Vantage 3.0.6 (think its a dev version), and I'm working with a cloned test site that I updated to v 4.1.3.
I've come across a strange problem. When I changed a featured image for a listing and tried to update, the listing would not update with an error saying the website url was incorrect. I tried several times to update, and had the same problem on other listings. I had to manually add "http://" to the beginning of the url for it to update.
Is this a bug? Is there a way to fix this without having to edit every listing manually?
TIA.
