Release 5.1.1
In this release, a problem with page-wide background images has been fixed
This release fixes a problem that occurred since release 5.1.0 when using a page-wide background image. When using an image, quite a few content elements were displayed without a white background. This has now been fixed with the new 5.1.1 release.
All site admins who had therefore temporarily removed the image can now set it again.
