hello all,
by reading again the instructions for installing the advanced mode I saw that it was specified that in phpbb/cache/ we have to let only the htaccess.
currently in that folder I have:
. htaccess
. htaccess.current
. htaccess.old
phpbb_cache.php
phpbb_cache.php.current
phpbb_cache.php.old
should I delete something?
thank you in advance.

phpbb/cache, not phpbb/phpbb_seo/cache where you should not delete anything (this is where all the seo settings and .htaccess are saved).

thank you for your answer, I understand my mistake.
In my phpbb/cache, in addition to my htaccess, there are also a lot of files like for exemple ctpl_admin_acp_main.html.php, should I delete all except the htaccess?
I thought that perhaps it was because of this that since I used advanced seo url the no archive fonction of the acp doesn't work?
