no, not at all... I thought I did - any idea what I missed if I did everything I mentioned earlier?
THis is from the install file
For a smooth install :
1) Backup all your files;
2) Apply the mod code changes on copies of your files;
3) Upload all files;
4) CHMOD the phpbb_seo/cache/ folder to 0777;
5) Empty the phpBB/cache/ folder : just delete all files EXCEPTS the .htaccess.
6) Go to -www.yoursite.com/phpBB/phpbb_seo/phpbb_seo_install.php and follow the install instruction
7) Go to phpBB ACP : It's now time to play with settings described bellow;
8) Generate your personalized .htaccess and upload or move it following the instructions;
9) Test a rewritten URL, such as -www.yoursite.com/phpBB/post1.html, if you end up with a 404 (not a phpBB message), go back to step 8;
10) Activate URL rewriting in phpBB ACP and allow yourself some auto-congratulation

and I did all of this. The exceptions were with #2, I actually uploaded the files first, then realized I needed to do this later and they all had the added code already - the SEO Toolkit stuff...
The other exception was #9 because, none of them appear to be re-written...
