Hm, thats strange... The following modules are used: ListerPro, ProcessWireUpgrade, Pages Sum, LoginPersist, Inputfield Decimal, Front-End Edit Lightbox I don't think that anything here changes the _() function   Is it possible to configure the "collection", that a edit modal is used, and not target=_blank?   /edit: ok i found it... when the LanguageSupport module is activated, the problem occurs. even if only one language is active
