NOTE!!!! Change for 3.6.10!!!
Technical explanation on CSRF changes
Because of this change, one line needs to be added to the PAGE template. You can either edit the template with the instructions below, or you can download the attached product-wired1_epfp(3.6.10 ONLY).xml, RENAME it to product-wired1_epfp.xml, and then install normally. As per any vB upgrade with this mod, when upgrading to vB 3.6.10 you'll still have to do the manual edits that are listed in the instructions again.
