t() strings need %placeholders or we can't translate anything.

The submitted string contains disallowed HTML: <strong>ClickandBuy</strong><br />Schnelle und sichere Bezahlungen mit Kreditkarte, Sofortüberweisung, u.s.w. <a href="http://clickandbuy.com/EU/en/info.html" target="_blank">Mehr Infos hier</a>.<br /><img style="margin-top:8px;" src="@image_url" />

This is the message that you get when trying to translate these strings:
