Hello. I am trying to troubleshoot issues with widgets not displaying int the admin area and I found your plugin on a list: WordPress Plugins Using PHP 4 Style Constructors.
Is that still accurate or have you updated the plugin. Thank you.
Simple Page Sidebars was updated well before the WordPress release that deprecated the PHP4 style constructors, so if you’re on the latest version, it shouldn’t pose any problems.
If it’s any help, widgets that still use PHP4 constructors shouldn’t stop working, WordPress just outputs a notice when debug mode is enabled.
