Hello,

I recieve the following error after plugin upgrate route66.

Fatal error: Cannot create references to elements of a temporary array expression in /home1/iamosoil.gr/plugins/system/route66/lib/router.php on line 61.

In 61 line is the following code
$canonical = $canonical->toString(array('scheme', 'host', 'port', 'path'));

To make my site up and running again I have rename the file plugins/system/route66/router.php but I don't kwon if this action create other errors to my site.

Please give me some advice how to fix this error.

Joomla version 3.8.12

Thanks in advance.
