I am setting up a SharePoint environment and have encountered an issue.
I'm trying to set up a simple form using web parts/html-form editor. However, when I try edit the form content, the "Source edit"-button is not working (i.e. nothing happens when clicking it). Also seen in added picture - the environment is unfortunately in Swedish.
I have also tried installing Form7, but encountered a similar problem; when trying to configure web part/content editor, the URL-button is "dead" - shown in second picture.
Any idea whats going on? Popup-windows are enabled.
