My form reverted to an earlier version of form. How to recover the form changes?

I worked for several hours perfecting a form to use.  I started with a clone of one I had working.

After modifying it and finally adding PayPal to it, I saved my form then opened in Preview and tried to test in Paypal's Sandbox.  

Paypal failed, so I returned to my form only to find that my form had reverted to the clone I started with.

Can you recover my work or suggest ways to protect my work from your buggs?  Saving doesn't seem to do the trick.

Hello DallasPPAPrints,

I would suggest you to please ensure that you have not logged into from two different browser and loaded the same form in both the browser editor. Please be noted that we have auto-save feature enabled which will always overwrite the version of another browser editor.

You can take advantage of our "Revision History" feature to revert back to an earlier version of your form. The following guide should help you:  http://www.jotform.com/blog/95-Introducing-Form-Revisions-Never-Lose-Your-Work-Again- 

Thank you!

I'm not sure you grasp the problem. I am the only one working on my form in only one browser. After much work, and after saving, after previewing my form IT retuned to a much earlier version of my form. 

I dont think revision history is applicable since that is the problem - the form reverted to the version I started with thereby losing all my hours of work on the form. 

I need the the latest version I created not the version your system reverted to. 

I found the Revision History and it shows the point where it says all the changes were made to the Form. What I'm trying to alert you to is that I did NOT make those changes - your system did. 

Your system has a rather scary bug, but at least there's a audit trail of sorts that can be used to recover. 

I'd prefer you eliminate your bug than my having to manage your mismanagement of an otherwise exceptional product. 

So, another bug found - while trying to post this answer, your system decides to "time-out", logs me out, and loses my post. But knowing about the fragile nature of the system now, I copied my text before posting.

Hi,

It might be that you had been logged out while doing changes so it was showing you the older version, while a proper version was saved in the revisions section.

Now this could be caused by your browsers cookie policy since you have mentioned that you have experienced this with forum as well when posting a question.

Do note that our system, like any, other depends on cookies to know what is your account username and allow you to post a question under your username. If the cookies get removed, the system can not recognize who you are.

Having that said, you should however still be able to post it even if you are not logged in.

I am glad that you have notifier us about this and we will be paying a closer attention to see if this is something others are experiencing as well.

Best Regards,
Ben
