On phpBB 2.0.x was it also the case that the only work with the default style , on that case it was subsilver.
Now it is prosilver indeed, and prosilver codes do not work on subsilver based styles.
So no it won't work yhe prosilver codes are diffrent (div , css style(s) )
You must edit it by your self, or in some cases have the mod author include a subsilver version.
Need phpBB installation, extenstions, Styles or integrate phpBB with you website?
for fair prices and good service!
