If I remember correctly, you migrate from a rather old installation that most likely didn't use the extended database schema. My best guess is, that you didn't upgrade your database to schemas.wview_extended.schema
See: https://github.com/weewx/weewx/blob/master/bin/schemas/wview.py => doesn't contain "maxSolarRad" vs. https://github.com/weewx/weewx/blob/master/bin/schemas/wview_extended.py => conains "maxSolarRad"

The skin's configuration is assuming having the extended schema, so now your options are:

Not using the predefined Chart
Using the predefined chart without "maxSolarRad", problem here: in this case I don't know any other solution than removing it in skin .conf. I'll check an improvement
Migrate to the extended schema, see: https://weewx.com/docs/latest/customizing.htm#transfer_database_using_new_schema

Mi Michael,

For now I've disabled "maxSolarRad" but my live gauge and Live charts still do not work.

I've restarted weewx with the same issue.

(...)

[[radiation]]
[[[radiation]]]
payload_key = radiation
#convertFunction = "function(value) { return value / 126.7; }" #you can do value conversions if needed
showMaxMarkPoint = true
showMinMarkPoint = false
showAvgMarkLine = false
lineColor = '#ffcd56'
decimals = 0
# [[[maxSolarRad]]]
# plotType = line #optional plot type, "line" is default
# payload_key = maxSolarRad
# showMaxMarkPoint = false
# showMinMarkPoint = false
# showAvgMarkLine = false
# lineColor = '#ffcd5677'
# decimals = 0
[[[UV]]]
yAxisIndex = 1 #to assign UV to the 2nd yAxis
plotType = bar #plot type, "line" is default
aggregateType = avg
aggregateInterval = 3600
payload_key = UV
showMaxMarkPoint = false
showMinMarkPoint = false

But I also have this error (not critical) :

Looking at https://ymartin.com/meteo/and https://ymartin.com/meteo/en, The gauges and charts l look just fine, with up-to-date data. The only thing: the radiation chart is not the. did you enable it in the live_chart_items = outTemp, barometer, rain, outHumidity, wind, windDir, radiation ?

But there is an other issue: if you check the errors (depending on the browser, press F12 on a Desktop) some files are not uploaded:

index.html:190 GET https://ymartin.com/meteo/en/js/jquery-3.6.3.min.js net::ERR_ABORTED 404 (Not Found)

index.html:198 GET https://ymartin.com/meteo/en/js/lang.js net::ERR_ABORTED 404 (Not Found)

Are these files in ../skins/Bootstrap/js?
