Trying to update or download syntax highlighting files results in the following error: "The list of highlightings could not be found on / retrieved from the server" The editor first tries http://kate.kde.org/syntax/update-5.36.xml This is redirected to http://www.kate-editor.org/syntax/update-5.36.xml which gets a 404. Looking in http://www.kate-editor.org/syntax/ shows that .xml files are present for up to 5.35. 5.36 is missing though this is the version requested by the current version in Fedora.
Fixed, thanks for the report!
