[SOLVED] Responsive Auto Responder Form Not Allowing keyboard on mobile devices

Hello,

I have been having trouble getting an auto responder form to work with this site here:

https://vivbounty.info/thosbartletts...subscribe-old/

I have just pasted in a new one that is responsive from my auto responder and it does size properly,
but now it will not allow the virtual keyboard to say up on my android phone, my husband's android phone and my Kindle.

I have asked my autoresponder admin about this and they seem to think it's the theme as they have not been able to find a solution in a year and are still working to do so.

Does anyone know how to fix this?

Thanks in advance for your help.
