Duplicate entries intermittently being created
We have had this issue for some time, and have not yet found enough of a pattern to explain the cause. We use Formidable Pro for various order forms on a website. So the same customers will order different things on different days, and it is not possible to just limit them to 1 entry forever. For example, they fill out their contact info and the product description they are requesting to get an estimate for. When they submit the form, it sends the order entry into the Formidable database as normal and also populates another order app that we built to track them.
The strangest thing happens - we see an exact duplicate copy of the same order appear minutes, hours, or even days later in Formidable entries. At first, there were a couple that were so close together I just assumed the user was double clicking submit by mistake. But since then we receive many different repeat cases and the customers have no clue why they are being called for the estimate twice. Sometimes they submit the order request, get a phone call and then 3 days later a duplicate of that request comes through again and they are surprised and confused they receive another phone call. They obviously didn't go back to the website and submit the form again days later. The info in these entries is exactly the same, except it is creating a new entry ID and inserting that as a new entry row.
It only happens to a handful of people each week (among hundreds of other entries), but every week it does happen. It is intermittent and kind of random.
We have tried to setup error logs without any clues. I am not sure where else to look.
We have Formidable core pluginVersion 3.05 and Formidable ProVersion 3.04.02 installed and activated on the up to date WordPress 5.0.3.
Any ideas are greatly appreciated!
