I am having the following problem, when i confirm an order in VirtueMart i get a blankpage with the following error " Fatal error: Call to undefined method VmVendorPDF::convertHTMLColorToDec() in..."
I have heard some people fixed this problem by upgrading to the latest version of VirtueMart but thats not what i want for now...
I was looking for another solution to this problem but if "Upgrading" is the only solution... i will like to know if it is safe to iUpgrade to a new version of VM in this template "StoreBox", i want to be sure things wont be getting out of place with the new Upgrade.
Thank you

Regards
