When I delete the following code (regarding point 1.2), all the information about the user pic isn't displayed anymore on the memberprofile.
//User Pic
"userpic_allowed" => $config['userpic'],
"userpic_img" => ($user_info['userpic']) ? ROOT_PATH."data/userpic/".$user_info['userpic'] : "",
"lang_userpic_del" => $lang['userpic_del'],
"lang_userpic_upload" => preg_replace("/".$site_template->start."userpic_max_size".$site_template->end."/siU", $config['userpic_size']." ".$lang['kb'], preg_replace("/".$site_template->start."userpic_max_width".$site_template->end."/siU", $config['userpic_width'], preg_replace("/".$site_template->start."userpic_max_height".$site_template->end."/siU", $config['userpic_height'], $lang['userpic_upload']))),
"userpic_max_width" => $config['userpic_width'],
"userpic_max_height" => $config['userpic_height'],
"userpic_max_size" => $config['userpic_size']." ".$lang['kb'],
//End User Pic
But I have entered the values fix in main.php (hardcoded), instead of the variables. That is ok for me.
Thank's anyway
