Sure, but troubleshooting will have to be done to determine the cause. I suggest you try the following:
Disable all modules except the weatherforecast module in your config.js file.
Disable all entries in your custom.css file except the one for weatherforecast.
Now see if the css entry for weatherforecast works.
@gwiz I don’t know
the code says
if (this.isInWindow(this.config.startTime, this.config.endTime, this.config.hideDays)) {
startTime defaults to 00:00
and endTime defaults to 23:59
and hideDays defaults to []
