Yes, there 's an issue with php V8 on the Form Builder. Hoping CC has an option soon.

This post was started in February, it's now mid-September and I still don't see any answers other than "they are working on it". My hosting company has already sent a notice that they will be moving to 8.1 as of December.

Hopefully, they are getting close,

I'm also concerned about this, I have contacted Coffeecup directly and this is the reply I got from Suzanne Norvell (Sales & Support Manager)

"Hello Chris,

We are working on an update for the Web Form Builder to run on PHP 8. We actually hired a new PHP programmer to help with the task. However, we don't have an official release date when the project will be finished. Unfortunately, I don't think it will be ready by early October.

As a work around, you could upload your files to S-Drive and paste the embed code into your website."

I hope the Coffeecup development team will deliver soon, else I'm going to have many upset customers should their forms stop working when my host changes to PHP8.X

Coffeecup suggest using their S-Drive, sadly there is a cost involved and at this stage I cannot afford it due to the number of websites involved.

Thanks for the info in this thread, guys. I found that a long-time form on a client's website had suddenly disappeared. I was able to set the PHP version back to 7.4 from the 8.1 that the host provider had automatically upgraded. I finally found it was that simple after spending a great deal of time trying to figure out what was wrong!

Web Form Builder v 2.10 Build 5575

Just changed hosting on a WP site. Form works ok on PHP 7.4 but does not display on PHP 8.

So I have the same problem.
