I am upgrading from Free to Pro and cannot install Pro. I get this error when attempting to activate the plugin:
Warning: require_once(/home/xxxxx/public_html/wp-content/plugins/bulletproof-security/includes/class.php) [function.require-once]: failed to open stream: No such file or directory in /home/xxxxx/public_html/wp-content/plugins/bulletproof-security1/bulletproof-security.php on line 76
The problem is caused by WordPress (PCLZIP) still thinking the BPS free plugin is still installed and then names the /bulletproof-security plugin folder with a number after the folder name. /bulletproof-security1.
