"An error occured when submitting. Please try again later." Signup form is broken. How to fix it?

Other websites that are using Klaviyo doesn't have those problems, asking my customers to turn off the ad block is not an option

no it dont’ when you using an adblock or have an iphone.
Maybe you checked it when I implemented omnisend

Are you joking here? you see if the problem was resolved there????

Why the form isnt visable on iphone at all for example?? Would be able to help me or you just say ‘mine works wine’ and you’ll send me some old topic when problem wasnt fixed??

Hi @Greg,

Thanks for your follow-up note.

To clarify, the rationale for linking you to the thread, was to provide some potential solutions which helped resolve this issue for customers in the past (not exclusively customers who have commented on that thread). Since it is a generic error, there could be a variety of reasons why it occurs.

I noticed you had reached out to our support team for further assistance. You mentioned the form was working without ad-block, and in light of that information, they mentioned an alternative solution:

“...utilize and implement custom/legacy forms built using HTML/CSS. Because custom/legacy forms are built from HTML/CSS and considered "hardcoded" onto your website, ad blocks would not be able to remove its elements and prevent the form from displaying...”

And some articles were provided for further assistance:

Legacy Signup Forms vs. New Signup Forms
Add and Customize a Legacy Embedded Form
Add Custom Fields to a Legacy Form

In short, it is clear from the testing that you performed (testing the form with vs without ad block) that the ad-block is causing the error to appear. While we cannot control what that ad-block does, we can provide the tools for a workaround. If you’d like assistance with putting the aforementioned custom form together, I recommend reaching out to our of our wonderful partners.

With respect to the iPhone issue, I would double-check the display settings for the form to ensure it is set to Desktop & Mobile. It may be that it’s simply only set to display on Desktop. This setting is located under the “Behaviors” tab of the sign-up form.

I hope that information is helpful.

And? I should ask someone to fix your poor service?
You still didn’t explain me how to fix that issue with adblock

"An error occured when submitting. Please try again later."

I read your articles and there is nothing up there about my issue - why you even sent me those?

Omnisend works great, only klaviyo is tremendously bad.
Why adblock causing that issue?
Can you check your logs or whatever you have here??

With respect to the iPhone issue, I would double-check the display settings for the form to ensure it is set to Desktop & Mobile. It may be that it’s simply only set to display on Desktop. This setting is located under the “Behaviors” tab of the sign-up form.

Obviously display is on on desktop and mobiles. Still on iphone you cant see the form
