editbutton.php line 55 fix

if ( is_null( $this->inited ) ) {

With

if ( is_null( $inited ) ) {

Dokuwiki says that $inited is Undefined, three times. I am not using the plugin in the node. The page had the include plugin and text (two lists).

{{page>:sidebar}}

Hi. I am using your dokuwiki plugin recently. Thanks for your work.

Open editbutton.php and inspect line 55, where the issue reports the undefined $inited warning. Reproduce the DokuWiki page setup with the include plugin and two lists, then verify that the warning no longer appears. The issue is done when this scenario no longer reports $inited as undefined.
