Hi, new to the forum. I have a Dropdown box that has been manually populated with choices to populate a field in a collection. The Dropdown box works correctly in Preview mode and correctly populates the collection with the selected choice. When Saved, Published and viewed live the dropdown box does not work. I am not using any Code, just the Wix User interface. The annoying thing is that it was working up until last night and without me changing anything it has stopped working. I have tried to delete/ recreate it but the same problem remains…Any help or advice would be fantastic thanks All the best Russell
Hi 
Did you make sure that you synced the involved Sandbox collection with the Live collection?
I think that might be the case.
Hi Ahmad, thanks so much for your reply. That was the problem, so pleased I posted on here. Thank you and enjoy your Sunday👍🏻
You’re welcome 
I’m glad that it worked, if you need anything again you can tag me and I’ll try to help as much as I can. You can follow me as well.
I don’t have Sandbox/Live activated. Just the old one database. But I’m still having this issue. Dropdown functions fine in preview, nothing on Live Site.

Check database-permissions.
Downgrade them for testing.
@russian-dima You are a life saver! I would have been up past midnight tracking this down! Know that you have made the world better tonight! 
At least for me!
