Settings=>Station Settings=>Graphs=>Data Series Visibility
Files to transfer to your website apparently are disabled by the new release so you have to walk through again, the most obvious given below (I think all is covered but you never know)
Settings=>Internet Settings=>Web/FTP Settings=>Realtime Settings You must tell CMX to generate and to FTP transfer both files
Settings=>Internet Settings=>Web/FTP Settings=>Interval Settings=>Standard File Settings are not required
Settings=>Internet Settings=>Web/FTP Settings=>Interval Settings=>Graph File Settings are required, you may disable availabledata.json and airquality.json
Settings=>Internet Settings=>Web/FTP Settings=>Interval Settings=>Daily Graph File Settings can all be disabled
Settings=>Internet Settings=>Web/FTP Settings=>General Settings Make sure you activate the UTF-8
Settings=>Extra web files: If you activated the Graph files above you may remove them here (if you entered them here because of a previous release).
This should get the whole thing balanced and working with only the required datafiles.
If you use e.g. the all-datafiles for another website then of course you do need to activated them. This is just about what is required for CumulusUtils.
