I had this plugin installed for a while. Once I from WordPress 2.9.2 to 3.5.2 updated the plugin to the latest version it gives me the following error each time I try to save.
Fatal error: Call to undefined function mb_convert_encoding() in /home/campsimc/public_html/site/wp-content/plugins/pie-register/pie-register.php on line 635
Also when the user logs in they get redirect to a page that doesn't exist. it should just be redirecting them to the referrer uri. I tried changing it using peters login redirects but it does not work.
We have hundreds of users that have custom meta info using this plugin and need to get this fixed ASAP.
Thanks for your help.
