Sulu Release 1.5.23 & 1.6.27
Both releases contain a fix, which caused redirects to mix up the used schema.
In addition to that the new 1.6 release fixes three more bugs. One appeared when you uploaded and afterwards downloaded a HTML file in our media section and the second was an incompatibility with PHP 7.3. Last but not least the copy webspace command now correctly adapts the links added in a teaser when being copied.
The 1.6.27 release also brings a new commands for removing outdated media cache files and introduces an event, that can be used to add more functionality to our cache clear feature.
