Message can′t be send –

Same issue here: https://bellaviavenue.com/contact/ – was working last week.
Not this week. Browser is Chrome.
Submit, hangs and hangs, no return URL. People keep hitting submit thinking it’s not going through. That’s a tad bit agitating.
Hangs in Firefox too.
Hangs in Safari on phone, too.

What can we do to resolve this hanging submit button?
Thanks.

OK but this form in www.ads-software.com doesn’t hang when we click submit.

I’m having the same issue. Hanging on all browsers.

Found my issue. I had a return URL script in there and I was missing a tick (‘). Added in the tick and it works perfectly now.

Where did you find it? I’m showing a syntax error on my form, but I have no idea why!

Go into your Contact in left.
Contact forms.
Select the form that is hanging.
