When clicking on "Embedded file", the "insert file" window pops up. But when I click on "upload" there, the window closes and nothing happens. This problem occurs in my 1.29.0 version, in a separate 1.28.2 installation (on the same server), the upload works fine.
In the browser console, I get the following error (in the 1.28.2 version, I don't get errors):
:Uncaught Error: Windows must have a `name` static property defined. load.php?debug=false&lang=en&modules=jquery.accessKeyLabel%2Casync%2CbyteLength%2CbyteLimit%2Ccheck…:537 at OoUiWindowManager.OO.ui.WindowManager.addWindows (load.php?debug=false&lang=en&modules=jquery.accessKeyLabel%2Casync%2CbyteLength%2CbyteLimit%2Ccheck…:537) at HTMLDivElement.wikieditor-toolbar-tool-file-upload (load.php?debug=false&lang=en&modules=ext.wikiEditor|ext.wikiEditor.core%2Cdialogs%2Cpreview%2Cpubli…:60) at HTMLButtonElement.props.click (load.php?debug=false&lang=en&modules=jquery.ui.button%2Ccore%2Cdialog%2Cdraggable%2Cmouse%2Cpositio…:24) at HTMLButtonElement.dispatch (load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=0ax79ee:65) at HTMLButtonElement.elemData.handle (load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=0ax79ee:60)
Is this a bug in the new version?
