Hi Daniel,
I checked the Slide Menu Marketplace page, and version 3.1.1 is listed as an available release. Since version 3.1.0 downloads successfully but 3.1.1 returns “Access Denied,” this may be a version-specific Marketplace download issue.
I would try the following:
- Download through Studio Pro: Open your app, go to the Marketplace, search for Slide Menu, open the Releases tab, and try downloading version 3.1.1 there. Mendix recommends using Studio Pro to download Marketplace widgets.
- Check your Marketplace session: Sign out and back in, then retry. You can also try an incognito window or another browser to rule out a stale session.
- Check whether the issue is version-specific: If 3.1.0 downloads successfully but 3.1.1 fails through both the browser and Studio Pro, the release download itself may need investigation.
- Contact the widget author: If the problem persists, report it through the Slide Menu component page or its linked issue tracker. Include the version number, exact error, and whether the failure occurs in Studio Pro as well.
My recommendation: Try downloading 3.1.1 directly through Studio Pro first. If you still receive “Access Denied,” report it to the component author or Mendix Support rather than modifying the widget or repeatedly reinstalling version 3.1.0.
Hope this helps.
