Nope. Sorry

Sorry Nigel, I have had an issue with it as well but never got around to fixing it... i'll look at it and will let you know

All we need is a forward slash at the start!

 src"/usercontrols....

Sorry if I'm stating the obvious as I'm sure you know that. But sometimes...you never know

PS - Reposted as previous message is breaking the forum!

Nigel, did you get it resolved then? Like i've said it's been a while. I don't even remember where the problem was so if that's all it needs to fix it then the credit is all yours!

I'll make sure to add it soon (i also need to upgrade the package to umbraco 7 anyway)

is working on a reply...
