PHP Fatal error

Thanks for reaching out. I’m sorry to hear about the error.

However, we could not reproduce the error in our test environments with the default settings. We could only reproduce the issue when we made some customizations, like manually requiring PaymentLinkService.php via functions.php. Please note that when the PaymentLinkService.php file is manually required outside the normal WPForms boot sequence, AbstractService is not loaded, causing the “Uncaught Error: Class “WPForms\Vendor\Stripe\Service\AbstractService” not found” error.

That said, the issue may be due to code customizations or a conflict with another plugin or your theme. When you get the chance, could you please try using the steps in WPBeginner’s detailed guide on troubleshooting WordPress to see if it helps resolve the issue?

Also, please share the details from WPForms > Tools > System Info (screenshot). This information may help us better understand the issue you’re experiencing.

If you have any questions, please let me know.

Thanks!

Hello -

Thanks for getting back to me.

The challenging part is that we are not using any payment setup. This is an error due to Stripe, but Stripe is not set up nor do we use it in any forms See screenshots below along with the information you requested and error logs below.

Thanks for sharing all the information!

However, I was unable to reproduce the issue using only the plugins available in the WordPress repository.

But using a custom code snippet, I can reproduce the issue with a simple form, even without payment.

Here is a screencast with more details.

The error on your site is likely due to a code causing a conflict with the execution of WPForms. The form should submit, but an error is reported in the logs because part of the plugin execution is missing. As you can see in the screencast, I can reproduce this issue with a small PHP snippet.

I recommend:

Create a staging site for your tests so that you don’t affect the live site. WPBeginner has a guide that explains how to easily create a staging site.
Disable all snippets under the Header Footer Code Manager plugin to see if the issue continues. If the issue stops, you need to review your snippets.
If the issue persists, switch to a default WordPress theme, such as Twenty Twenty-Five, and see if the issue persists. If the issue stops, you need to review your theme.

I hope this helps! If you have any questions, please let me know.

Thanks!

I checked and we only have 4 snippets for tracking information. None of which seem to be causing this fatal error.

PHP Fatal error: Uncaught Error: Class “WPForms\Vendor\Stripe\ApiResource” not found in /home/jeffre66/public_html/wp-content/plugins/wpforms-lite/vendor_prefixed/stripe/stripe-php/lib/Issuing/Cardholder.php:28 Stack trace:

Is there a reason that this would not be found? As previously mentioned I have unistalled and reinstalled WPForms several times and have also tried to upload it directly to no avail.

The issue in this case might be a code conflict with your “Services 1.0.0” theme.

When you have a chance, please test for a theme conflict. If it helps, we have a guide with details on how to do so.

To prevent affecting your live site’s appearance or functionality, I recommend using a staging site for your test.

Another option is to use the Health Check & Troubleshooting plugin on your site. It offers a quick and secure way to replace your theme and deactivate your installed plugins without affecting your live site’s appearance or functionality. You can learn more about this plugin here.

I hope this helps!
