Hi,
I had been using my site fine with this plugin but someone reported that when they tried inputting in to the Contact Form (Contact Form 7 Plugin) on a mobile or tablet device (PC/ Laptop is fine) that they were unable to enter any values to the boxes.
I investigated and after disabling this plugin it started working fine.
Contact Form 7 is quite popular so it would be good if these plugins worked together.
As I said, this is an issue only on mobile devices.
