There is a new version of Grid that is on wowace and in the curse downloader. However, this new version is NOT the same as the one listed on the Curse website OR listed on wowinterface either (updated 4/16).
The 4/16 version works with all plugins that I’m currently using (hint: it’s a lot). The newest version is not playing nice with Gridstatuspwshield, Gridstatusmending, Gridstatusself, and a few others. I’m not going to say that the new grid is buggy – just that from my personal observation it’s not compatible with some plugins.
If some of your plugins have inexplicably quit working, you might want to try reverting your grid version to the 4/16 version (on the curse or wowinterface website) and see if that helps.
