Gravity forms is a great forms plugin for WordPress. I purchased a licence and it lapsed, but I still use it on my website. The problem is, because the licence is lapsed, I am seeing an ugly, annoying message saying that my copy is unlicensed. Just to clarify, I did buy a licence, and I am allowed to use the copy, I just don’t want to renew it for a new version.
To remove the nag, it’s a bit tricky, Gravity Forms have gone above and beyond to make it difficult for people to do to protect their bottom line and just annoy someone to eventually re-licence.
However, with that being said, just add this to your functions.php file.
/** Remove gravity forms nag */
