I accidentally reverted the global.css and now my board looks very ugly. I need the global.css for pronavy please.
The ProNavy theme contains copyrighted images, so I don't suggest using it.
I'll suggest, download the theme again, Install it on your forum with different theme name, copy the code from global.css and paste it on your current theme's global.css. After doing this successfully, delete the theme and its templates from ACP > Themes & Templates
