[Plugin: Get Post] Fatal error: post-class-get-getter.php on line 128

when I use the [get-post] command in any page or post in site, when i save the page or post, this message appears:

“Fatal error: __ clone method Called on non-object in / web / htdocs / http://www.progettoiltempio.it / home / wp-content / plugins / get-post / post-class-get-getter.php on line 128”

Only disabling the PulgIn, making changes and then only after all the work, re-enable the PlugIn, it will not be this error.

With the version I used before this error was not displayed
