Contact Form 7 Not Submitting On Mobile Devices


We have a contact form that has functioned perfectly for several years and just recently it began malfunctioning. When submitting a form from desktop, the contact form still functions properly, however when trying to submit the same form on a mobile device (specifically iPhone - I don’t know about Android devices) the form does not go through. I’ve already updated everything, including PHP and I’ve ruled out any interference from other plugins. Can you please help? Thank you!

Hello @Zaepian,

Thanks for writing in! You have installed the W3 Total Cache plugin. This could just be a caching issue. It could also be caused by a plugin conflict, amongst other things. Please check out this troubleshooting article here and follow the instructions for the following sections (where appropriate):

Testing for Plugin Conflict

Disabling Cache
Disabling CDN

It appears that the issue is that reCAPTCHA response token is empty when using mobile and so Flamingo is filtering the messages as spam. Do you know how to fix this issue? Again, it’s working fine on desktop, but for some reason it’s not working on mobile…

Hi @Zaepian,

I suggest that you create a new site key and secret key for your recaptcha and let see if it fix your issue. You can do it here.

Hope that helps.

Thank you.
