I came across this today. If there is a problem, is there something I should be doing to minimise the risks? My forum is using version 3.4.07 which is the one mentioned in the linked page.
OK sorry about that, I just looked at the date at the bottom of the linked page, 2015-03-25 and assumed that this was an issue that had cropped up since I started using the software in 2013. Thanks for putting me right.
