Folded use of the deprecated document.write() method causes console error when URL rewriting is on (.htaccess)

[barredespace]

With Folded activated and userewrite=1 (.htacess URL rewriting) I get the following message in console :

js.php?t=notos&tseed={{hex}}:1 Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.
(anonyme) @ js.php?t=notos&tseed={{hex}}:1

No other obvious effect on page. Folded still functions.

When I deactivate Folded, the error disappears.
