I am just curious.... Which localhost server do you use for xenForo? Xampp, Zend or Apache? for me, i am used to Wamp. However friends told me there are no support for ApacheTriad anymore.
I had the same thing, I think but it wasn't Skype related.I've used XAMPP for years.
The last time I tried to install ZEND I had a port issue which I couldn't resolve.
I think it may have had something to do with Skype so I'll give it another go.
