Hi Team,

My pop up comes up on our wordpress/ woocommerce site, however when a customer enters their email to subscribe in the pop up they receive an error message that says “An error occurred when submitting. Please try again later.”

The pop up intitially worked for 4-5 months.

I have cloned the pop up, taken the pop up off and redone, cleared caches, we are using the most updated version of browser.

I do get their subscribed emails in my klaviyo list, however they do not get the “success pop up” with the coupon code on it.

Can you point me in the right direction on how to fix this issue, thanks.

Cheers

Tanya

Hey @tanya5

Can you please check if the “List” is selected in the button’s action settings? if that is not set, then the emails dont go anywhere. When you test: use a completely fresh email in an incognito window. Not your own email, not one you've tested with before.

If this still doesnt work, and the List is set correctly, pull up your browser console while you submit (F12, Console tab). On WordPress and WooCommerce sites, caching plugins and cookie consent tools have a habit of swallowing the form response before the success step loads. If you spot a JS error in the console right after hitting submit, that's the problem.

Since I cant see your account, its difficult for me to point out what is happening on your backend, so if none of this works, Klaviyo Support is the right next step ( cc @Byrne C )

I hope this helps and thank you for sharing your question here in the community.

Cheers,

Arpit
