Include issues with wp-content, causes plugin to break

Please use the following function instead of directly using wp-content when specifying your plugin’s file location.

There are several instances of this throughout your code, and your plugin breaks if you rename wp-content using a security plugin.

Example from your codebase:

DEFINE(‘EASYCONTACTFORMS__fileUploadDir’, ABSPATH . ‘wp-content/plugins/easycontact_templates’ . $ds . EASYCONTACTFORMS__fileFolder);
