 * Hello,
 * I’m seeing an error which seems to be triggered by this plugin.
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, no
   array or string given in /{–site-root–}/wp-includes/class-wp-hook.php on line
   298
 * I disabled all plugins and managed to remove the warning message, then gradually
   switched them back on, isolating Collapsing Pages as the cause. I’m running version
   1.0.1.
 * Please advise,
 * Many thanks, Jerry
