I have had these forms on a client's website forever now and have had very few issues until now.
There was a server switch and I proceeded to update the SMTP settings and everything seemed to be working fine until today. The client emailed me to say that the website is hanging when the submit button is clicked. Of course, I then tried it out myself and it did NOT hang for me. I tried several browsers (Chrome, Firefox, IE) and all of mine went through.
Still, my client and everyone at her office is getting the "one moment please" message whenever they submit the form.
I told her to check for popup blockers and she says they are not on. There was also a client of hers in another state who also could not submit the form. Everything works on my end though, which is weird.
Any idea why this is happening and how to repair it?
