I was trying to change the Logo Image Location from the default and noticed that it didn't change the settings after saving. I then noticed that none of my original settings were there.
Using: PHP5.3.2
Apache Error Log:
PHP Warning: Parameter 1 to ws_plugin__s2member_pro_options() expected to be a reference, value given in /var/www/leenk.me/wp-includes/plugin.php on line 166
I removed the s2member-pro folder and everything is working again, but I had to reset all my settings. But they are saving now.
