Plone: Upload File mechanism is disabled by default

How to ... enable the "or upload a file (existing content will be replaced)" text field and Browse.. button in Plone.

Apparently this text field and button was causing confusion amongst neophyte users ... so was hidden.

To get it back is achieved by editing a style sheet.

  • Go to Plone/portal_skins/plone_styles/
  • Save a copy of ploneCustom.css ... which will appear in /portal_skins/custom
  • Open it and add the following text

    .fieldUploadFile { text-align: right; margin-right: 0.75em; display: block; }
  • Save it and reload your browser (to remove any cached versionof this style sheet
  • voila...
