An error occurred while processing the form

Hi @donniepeters

I hope you’re well today and thank you for contacting us!

I’ve imported the form to one of my test sites to test it but I must say I wasn’t able to replicate this issue on my end. I don’t see anything wrong with form configuration either and no errors in browser console on your site. Everything looks to be in order.

However, let me ask as these parts of configuration are not included in export:

1. Do you have any integration (such as e.g. Google Sheets, MailChimp or any other of the available integrations) for the form? if yes, what integration is that?

2. Are you an anti-spam solution on site such as either Akismet or CleanTalk Anit-Spam?

Also, could you try a small change in settings of the upload fields (both of them) and check if that makes a difference? Those changes would be:

a) switch upload fields from “single” to “Multiple”
b) then set “Limit number of files” option in field settings to 1
c) and make sure that “Upload method” is set to “Ajax” there.

Since we are at that – do you know by any chance how big files they tried to upload via the form (and were files of this size or bigger already uploaded through this form before successfully)?

Best regards,
Adam

Hi @wpmudev-support8

Thanks for looking into this error.

1. I have no integrations attached to the form at all.
2. I use Wordfence and your question triggered something I did see in the logs for that. It showed that the submitter triggered a “tried to access /wp-admin/admin-ajax.php” message… I think – the logs for that are long gone but it only happened once or twice and not the same number of times that attempts were made as it would have blocked them as I have the limits set really low.
   

They were using only the one Upload field upload-1 which is set for Single, All Images, plus .webp, Max file size 134 mb, Show in Media Library enabled and the setting for Ajax upload is not shown due to the limited file types I am assuming. I do not want other types of files in this field.

upload-2 is set for all document types, 134 mb file size Ajax enabled and Show in Media library disabled.

All files added into upload-1 were all .jpg and ranged in size from 25.3kb to 3.5 mb. In total 8 submissions made it through but it took around 17 attempts and I used a remote access to their computer to watch them submit and saw it myself while watching the Debug logs on my end which showed nothing.

So the only thing is the Wordfence message I noted above. I am at a loss for a cause on this.

@wpmudev-support8 I just took a closer look at the Media Library and noticed that there are multiple copies of images for submissions that never made it through. One in particular was a 31mb image that failed in the upload.

And this is how it looks in the media library

The second image that upload for a failed submission was only 652kb which successfully uploaded

In total I have 31 images in the Media Library for 8 successful submissions which means that 23 failed attempts.

Another possibility is that I did change what happens after submission to a Redirect page which has a link to the form so submitters can click it to go back to submit again easier. On successful submissions the form does not redirect for a few seconds.

Hi @donniepeters

I see some errors in the browser console on the page where your form is located. I’m not able to replicate them on my lab with your form. Which means something on the site triggers those errors.

Each site is for sure different as it possibly uses different plugins or themes. In the WP repository, there are over 60,000 plugins, and some of them possibly exist on that site. Taking this into account, with each update (Forminator or other plugins) there is a risk of new potential conflicts.

Would you please run a conflict test? Please deactivate all plugins except this one and check if the problem is gone. If so, then enable all plugins one by one and find which one is having a conflict. If there is no positive result, switch to the default WordPress theme like 2019, and see if it works.

Before this test, we recommend full site backup or running this test on the staging site.

Please let us know about the results.

Kind Regards,
Kris

@wpmudevsupport13 thanks for your help.
I had not been able to duplicate the error on my end either even while testing at the same time as the one submitter was getting errors.

I am going to be using the form today to create multiple submissions that they did not finish as they got frustrated. Yesterday another submitter managed to submit 2 without errors.

Will see how it goes. The form worked fine the last 2 years for over 200 submissions without errors.

Hi @donniepeters

We haven’t heard from you in a while, I’ll go and mark this thread as resolved. If you have any additional questions or require further help, please let us know!

Kind Regards,
Kris
