The implementation of Dolibarr in IPV6 is working but sometimes there is a Problem that is coming such as: Access refused by CSRF protection in main.inc.php. Referer of form (http://[2001:8f8:1123:ccf6:3c94:bace:e987:4623]:9091/dolibarr/ecm/index.php?idmenu=29&mainmenu=ecm&leftmenu=) is outside the server that serve this page (with method = POST). If you access your server behind a proxy using url rewriting, you might check that all HTTP headers are propagated (or add the line $dolibarr\_nocsrfcheck=1 into your conf.php file to remove this security check). can this solve the issue? $dolibarr\_nocsrfcheck=1 ---

You provide several url saying it works, but can you provide 1 way to reproduce the trouble (and only one) ? And describe the full step you do to reproduce the trouble ? ---

hello @isoscent it seems that you are asking me about this by private messages instead of here. i dont understand your problem, and you said two years ago that you solved it ! EDIT : it seems that it is the forum engine that is making a mess !
