If you have installed Word Press and get the message “You do not have sufficient permissions to access this page.” because you have created a link for a subscriber to login. If a subscriber tries and login again using the link they will get the error mesage “You do not have sufficient permissions to access this page.”
Look at the file menu.php in the folder /wp-admin/ and edit one of the last lines in the file
wp_die( __(‘You do not have sufficient permissions to access this page..’) );
Replace the text and maybe add a link to help the user back to the main part they subscribed to the below.
wp_die( __(‘You are already logged in, please visit the <a href=”http://website-address.co.uk/members-area/” title=”members area” >Members Area</a> to see the content.’) );
Hope this helps and is a quick fix to a simple problem!
