You've made some progress
What is the problem that you can't do the CUtags.php?
I see that you have a separate site for your CumulusMX default template. That seems to work ok except the graph popups also don't display in the Gauges, and NOAA reports don't display.
Do you have the NOAA reports being uploaded to your site? and are they in the folder /noaa/NOAA-reports as your settings indicate?
let rptPath = 'noaa/NOAA-reports/'; /* cesta k souborĹŻm NOAA s koncovĂ˝m lomĂtkem */
as they do not show in

I run the CumulusMX default template and the MXUI template on the same site and that works quite well for all the charts, etc.
Whenever I install or update MXUI template I first make sure the CumulusMX default site is working ok - i.e charts, new features, etc., and then it makes it easier to resolve any MXUI issues if that were to occur.
