Apart from a few gotcha's like ports being renamed and missing database files. There was a odd ftp issue where it wasn't uploading even though the ftplog said it was. I checked the server end and there wasn't a connection. Restarting it fixed that.
I'm still using the old templates as I modified them.
Anyway I look at the new templates before modifying them. So I copied trendsT.htm from the mxfolder and renamed it to trendsaT.htm told it to process it in real time and use UTF8
So the path is C:\Program Files (x86)\CumulusMX\web\trendsaT.htm and the remote filename /trendsa.htm
The end result in mxdiags is illegal character in the path.
Eh?
If I do the same for a old template
C:\Program Files (x86)\CumulusMX\web\live_weather-ipadT.htm remote filename /live_weather_ipad.htm it process's it quite happily.
And I found the issue copying and pasting put the a tab in the path grrrrr.
