I just tried installing the plugin but following error appeared:
Error: Unsupported version
The plugin "Background Manager" requires PHP version 5.3.0 or better, but version 5.2.17 was detected.
Because of this error, the plugin was automatically deactivated to prevent it from causing further problems with your WordPress site.
Error source: /home2/trinegar/public_html/towerstreetdrama/wp-content/plugins/background-manager/background-manager.php
Please could someone help.
