Register button disabled

Hi guys,

I’ve searched around for this but found nothing similar. For some weird reasons when our customer wish to register and checkout the register (submit) button is greyed out. So did some further digging and it only happens when password is typed in to the password box. I’ve attached a shot of the inspect element to show this.

Has anyone experienced this before? Any recommendations? I’ve already gone over the plugins to make sure that none of them are causing it + enabling registration for WordPress which is enabled.

Thanks in advance
