I thought you may want to know that if I have JetPack enabled I get all kinds of error messages when I send a message using Contact Form 7. The message gets to the place I sent it but there are about 2 or 3 pages of error messages on the Contact Page after I send it. If I disable JetPack it is OK. I have uninstalled both Contact Form 7 and disabled JetPack and the results are always the same. Works fine without JetPack and gives errors with JetPack.
