Ad dates not working, defaulting to 1970

What version of AdRotate do you have?
Does it happen to new adverts only or also when editing?

I have the latest version and I see that creating new banners works fine. So we’ll get rid of the old ones if they became corrupt. Or is there any other trick?
Thanks

Should work either way – But if making new adverts is quicker then that would be my preference.

Otherwise check the servers error_log file for errors. Anything mentioning AdRotate is interesting. The error_log file can usually be found in your hosting dashboard somewhere.

I saved the advert and I get this. Please check:

That suggests no schedule is found for the advert as you load/edit it.
AdRotate doesn’t just delete schedules or anything though.

Perhaps something got corrupted in the database, or someone/something deleted data from it. If those errors don’t pop up in the log when you create a new advert and then still not when you edit that new advert AdRotate works fine.
