I know that this problem is kind of common but I didn't find a way to fix this problem.
I've install phpBB SEO 0.6.8 on phpBB3 3.0.9.
I configurate phpBB SEO via ACP to set all to 'yes' exept 'Activate SQL rewritting' and URL rewritting type is set to Advanced.
I didn't change anything in Forum URL Management.
I've generate my .htaccess that I copied and paste in my .htaccess in the root directory of my project.
Still, the links url do not change...
Please help me!
