MotoPress uses jQuery and jQuery UI with WordPress. Minimum jQuery version - 1.8.3. Minimum jQuery UI version - 1.9.2. Please update WordPress to version 3.5 or higher

After release of WordPress 4.1 we've collided with some compatibility issues and
released the new version 1.5.8 with bug fixes. To void these issues you need to update MotoPress Content Editor plugin.

2. go to Dashboard -> Updates and press "Check Again" button
3. find MotoPress Content Editor in the list of plugins and update it
