Thank you!

We've found the problem. It'll be fixed in the next version release. 

If you need to solve it asap please follow the steps below:

1. Open the wp-content/plugins/wpforo/wpf-includes/functions.php file

2. Find the is_wpforo_url($url = '') function 

3. Replace the following one:

function is_wpforo_url($url = ''){
	if( wpforo_is_admin() ) return FALSE;
	if(!$url) $url = wpforo_get_request_uri();

	if( WPF()->use_home_url ) return TRUE;

	$current_url = wpforo_get_url_query_vars_str($url);

	if( WPF()->permastruct && strpos($current_url, WPF()->permastruct . '/') === 0  ) return TRUE;

	return FALSE;
}

You were aggressive against me. And then you're surprised by my answer.

The conflict between wpForo & WP permalink structure is a fact! This problem also appears on a clean installation of WP with only one active plugin - wpForo. Why do you deny it?

This is a big problem for wpForo and a small one for me.

Please, read the full conversation before advocating!!!

Is your WP permalink structure set to: site.com/sample-post/ ?

If YES, please send me a post whose link starts with the slug of your forum.

And again, here is a clean installation of WP with JUST one plugin: wpForo.

This example site will disappear after 24 h.

@envi Please watch your language. I'm not advocating anyone. I also spend 10 minutes to check your site and possibly help.

I think some people do not deserve any replies here.

Sorry for the trouble, good luck.

Conflict wpForo with WHAT ? Wordpress ? I don't see any of this anywhere and i run 2 forums for myself and i have also installed wpForo, i dunno, in 10 sites or something.

All i have seen is conflict with other plugins, SEO plugins or strange/wrong permalinks configuration.

Also you seem to run W3TC and that plugin only puts a huge ammount of changes in htaccess mod_rewrite ... so .....

If I change the base URL, I think this will generate a lot of 404 pages on my website. And maybe this is not a good solution.

So I disable all plugins, delete all caches and so on. Nothing. This problem disappears only when I disable wpForo.

I have recreated this problem on 2 test sites too with just one active plugin on them - WPforo. The same situation.

WP Setting > Permalinks: Post name.
WPforo slug: forum
Regular Post slug: forum1

And the post is not open. Instead is open the 404 page of the forum.

Test site 1:
Forum: http://fragile-iguana.w5.poopy.life/forum/
Regular Post: http://fragile-iguana.w5.poopy.life/forum1/

Test site 2 (access code: 000):
Forum: http://plugin-tests.qsandbox.com/forum/
Regular Post: http://plugin-tests.qsandbox.com/forum1/

Please, help me with this!

Ok, then follow to my post above and change the base URL, then delete all caches as I described: https://wpforo.com/community/how-to-and-troubleshooting-2/regular-pages-of-my-site-open-as-404-pages-of-the-forum/#post-28815

This is not wpForo issue, this is a conflict with wpForo.

When I disable wpForo, this problem disappears. And all 4 posts are opening properly.
