I've tried for many hours now and am completely fed up. I've watched the youtube tutorials that are available; I have talked with my host; nothing appears wrong but none of these work. I've tried over and over to upload and then install the Xenforo Resource Manager; no luck. Then same for XenPorta. I've uploaded all correctly and into, for example, correct directories for XenPorta: the js contents into js folder; the library contents into library folder; the styles contents into styles folder. But then on trying to install addon, putting the correct file into the field: library/EWRporta/addon-EWRporta.xml then install, I get this: Error Please enter a valid file name. The requested file could not be read. What the heck?? I"ve never had so much trouble with a piece of software. Some people suggest doing the uploads differently. Some say upload all contents of the upload folder straight into the root directory. Some say separately upload the js contents, the styles and the library contents. Who is correct? Well I can tell you, none of these methods are working for me, and I'm wishing to heck I'd never heard of XenForo!! I"ve wasted a week and $200 on nothing! Can anyone give me sensible clear advice as to what might not be working here?
