Forum Some problems with forum by v.4.20
 

Dear members,

yesterday I upgrade my forum to the v.4.20 from v.4.15

I have to following problems :

When someone press the button home instead from the home page redirect to activity scream page (forum/activity.php) ,


When I insert a lot of links to one post I have the following error message (403 Forbidden) : Forbidden

You don't have permission to access /forum/newreply.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Please help me to solve the above problems
