Hello!
Do you have icons in the right folder? You said you had your icons in conf/icons/basic, but icons should go to conf/icons/classic. The folder classic should not to be confused with Classic UI. It is folder for Classic icon set, not Classic UI, so, if you are using Basic UI, you should not put icons in conf/icons/basic, but conf/icons/classic too. And few remarks:
- Don’t use uppercase letters for icon names
- Don’t use blank/space in icon names
- Don’t use hyphen in the name - only use it if you have dynamic icons (i.e. soundlevel-10, soundlevel-20) - you can use underscore instead
Hope this helps.
Best regards,
Davor
