An investigation into the error that a few FBP users were experiencing, where they would receive the script collision error message, “you appear to be running 2 versions of FBP”, even though they only had one version of FBP installed, revealed a solution to the problem.
Basically it seems its AVG antivirus interfering with the Facebook page, causing posts 2 appear twice and also to make the script run twice, which causes the previously mentioned error.
The solution is to uninstall AVG antivirus, install Avast antivirus instead, as it doesnt interfere with other programs so much, and doesnt slow the computer or use up so many resources.

**UPDATE** This error can also occur after FB Purity has just been updated, either manually or via an automatic update. This is a glitch, and im not 100% sure why it occurs atm. Basically, if you reload the page and the error message does not come back again, then you can safely ignore this error. If however the error message comes back on each page reload, then you definitely have 2 versions of FBP installed, and will need to remove one of them.
