Hi there,

Your site is actually listed on our piracy tracker as having an illegal version of Advanced Post Thanks / Like and vBShout - we checked manually and there are indeed unlicensed Pro files for these products on your server.

For obvious reasons we are unable to support people using illegal versions of our software, please purchase licenses for these products to use them legally.

Regards,
