Wrong readmore link from getReadAll() when no query string

[ReLater]

Plugin settings

Tag in Article

{qlwiki url="https://de.wikipedia.org/wiki/Joomla"}

Result

The readmore href is empty instead of https://de.wikipedia.org/wiki/Joomla.

Reason

$url = substr($this->states['url'], 0, strpos($this->states['url'], '?'));

returns an empty string because strpos($this->states['url'], '?') returns false when there is no ? in url.

Temporary solution in method getReadAll()

// get basic url without parameters
if (($strpos = strpos($this->states['url'], '?')) === false)
{
	$strpos = strlen($this->states['url']);
}
$url = substr($this->states['url'], 0, $strpos);
