Looking at your web server page I’m not sure if I install the old version and then then new version or just install the version with the dependences fixed? Basically I have 16.04 and mySQL

Also not sure about the whole mythexport web page? I know about mythweb for changing recordings and looking at upcoming shows, etc, but not about mythexport web page.

Anymore data on that would be helpful.
