@sdetweil I am running raspbian (debian 11 bullseye) with no pending updates on a pi3B+.
I have cd’d into MagicMirror/fonts, run npm install and restarted the MM. No change. Still displays a square where there should be an icon.

@sdetweil Apologies for the delay coming back to you. I do have a custom css file but not for the icon. The only changes in my custom css are for the calendar, moon phase and weather temp colours. Further to this I have not had this issue when performing previous updates.

Further to my brief outline of the problem - I followed all instructions for update from the official documentation pages, backed up my custom css and config files along with modules, performed update successfully, then reinstated my backed up files and noticed that the weather icon odes not show anymore.
Is there something in the settings / config file that has changed and I should be setting?

Weather Icon does not display on the current weather after latest update.
Rapsberry Pi 3B+

@enderflop further to before mentioned, I have changed my location in the js file from the standard US location you had and if I leave my location out of the config file I get an image(not sure if this a correct image or generic) but when I add my location in the config I get the no image message.

@enderflop I have given this a try and all i get is the No Image! message. Any ideas?
