I have a client who is using Ninja Forms and for whatever reason, I can select a date (any month) on the 1st through the 6th, but any date past then, it prompts the error "Please enter a valid date"
I've tried changing the date format, and I've ensured that he's using the latest version of the plugin. I've deactivated it, reactivated it, and checked their FAQ / known issues and haven't found anything.
Any insight would be very helpful. Thanks!
I fixed it. It turned out that (for whatever reason) the date format that had been working just decided not to. I changed it and then it just worked. None of the preset formats that come loaded with Ninja Forms would do it, so I decided to attempt others on the off-chance that it made a difference.
WordPress, am I right?
