Ok now i cant change Forum base URL, when i click on update one "\" appear instead of the default mysite/community/

🙁

Ledidic,

I'm not sure what are you doing wrong, but I'm sure it doesn't have any relation to wpForo.

Please create a new page with /somethingelse/ slug and try to call it. Forget about forum. If you page works fine then put [wpforo-index] shortcode in that page content, then go to wpForo Settings and put the full URL of that page to Base URL setting option.

i have tried all that things but the point :

go to wpForo Settings and put the full URL of that page to Base URL setting option.

doesn't work, instead of  my URL i have " / " after click to update (joined a screen)

What are you adding? It should be http://example.com/pagename/

It should not be

• example.com/pagename/
• http://example.com/
• http://example.com/index.php

no only this URL  http://rpgers.fr/community/  

same like the permlink of my page

and it's disapear when i click on update
