I started using sublime text v3 and I'm having problems with some extensions. When I look for php/js/css/html extensions, they aren't listed in the extensions list. I reinstalled the program and they're still missing. How do I fix this?
In your account's home directory open your application data or "application support" folder in Mac OS, then locate your Sublime Text folder. There should be a Cache subfolder in there, delete its contents, then quit and restart Sublime Text.
