Re: buddypres doesn’t work
Looks like you’re on single WP. Are you on Linux or Windows server? Have you checked out this Codex info – https://codex.wordpress.org/Using_Permalinks?
Deactivate BuddyPress and resolve permalink structure first.
Open up your site’s .htaccess file and compare it to example in article above. If different, then save a copy of your .htaccess file to a safe place, and replace what’s in .htaccess file in your server with what’s posted in article above related to your server setup.
If that doesn’t resolve your issue, you can get more assistance at https://wordpress.org/support/forum/how-to-and-troubleshooting
