vBSEO causes Problems and redirects to 404, when calendar rewrite rules are enabeled.

This can be fixed by editing either the product.xml or later the plugin calendar_getday_event an there replace

			// Prevents User Response Removal on redirect
			if (!preg_match('/redirect/',$vbulletin->url)) {
				$vbulletin->url .= "&redirect=1";
			}

with

			// Prevents User Response Removal on redirect
			if (!preg_match('/redirect/',$vbulletin->url)) {
				$vbulletin->url .= "";
			}

Best regards,
Alex
