A bug in the Wordpress version of vPIP was found that can appear under some circumstances where older posts have the vPIP Vlogsplosion entries messed up. This has been fixed in the 1.11b release now available. If you installed a version after 1.10 and before 1.11b, it's advised to install this release.
