@aplusvaservices You’re using WordPress, that’s what happened. A clash between the two plugins would be the obvious answer, but with wp the obvious isn’t always right. A weakness is in your theme’s code may have been exposed and you might be surprised by how little it takes to throw things out of whack.
For example, just having a space or empty line after the closing ?> tag at the end of the php file will cause header errors. Mismatched <div> tags can cause some crazy errors as well.
Try going to the contact page and have a look at the source code to see what’s being generated when the new plugin’s activated. You might find a clue to what’s wrong.
