Call to a member function mt_clear_cache()

Hi all,
I just bought your Plugin an I’m facing the same problem. My php-version is 5.6.21 and my sql version is 5.5.49. So what else can cause this error everytime I want to save? Thanks for your help.
Regards

Hi,

To all having the same problem: Fatal error: Call to a member function mt_clear_cache() on boolean…. A possible workaround is to add $maintenance = new maintenance(); before $maintenance->mt_clear_cache(); in plugin-folder/includes/admin.php function mt_register_settings(). Since mt_clear_cache() is a public static fuction, we need to initialize the variables.

The function mt_register_settings() in admin.php should be like this (after the change):

function mt_register_settings() {
		global	$maintenance;
		if ( !empty($_POST['lib_options']) && check_admin_referer('maintenance_edit_post','maintenance_nonce') ) {
			if (!isset($_POST['lib_options']['state'])) { $_POST['lib_options']['state'] = 0; }
			else {	   $_POST['lib_options']['state'] = 1; }

			if (isset($_POST['lib_options']['htmlcss'])) {
				$_POST['lib_options']['htmlcss'] = wp_kses_stripslashes($_POST['lib_options']['htmlcss']);
			}

			if (isset($_POST['lib_options'])) {
			    update_option( 'maintenance_options',  $_POST['lib_options']);
				$maintenance = new maintenance();
				$maintenance->mt_clear_cache();
			}
		}
	}

I`m using php 5.6, btw.

And great plugin. Thank you.

I am getting the same error, with PHP Version 5.6.23
