PHP error when page content changes

[opusman]

I get the following error after changing the content of a page, pressing F5 to refresh twice fixes it.

PHP Warning:  Undefined array key "metadata" in C:\inetpub\wwwroot\manual\lib\plugins\pagetitle\syntax\decorative.php on line 146
PHP Warning:  Undefined array key "xhtml" in C:\inetpub\wwwroot\manual\lib\plugins\pagetitle\syntax\decorative.php on line 146

Fixed by adding the following at the top of the render() function in decorative.php:

		$counter['metadata'] = 0;
		$counter['xhtml'] = 0;

We were also affected by this warning, so we disabled the pagetitle plugin in our deployment.
