Open the Templates window Click the Browse online templates button in the bottom left corner. The https://extensions.libreoffice.org/templates/en page opens when UI is en-US and https://extensions.libreoffice.org/templates/hu when UI is hu-HU. But neither of these is valid, I get: This page does not seem to exist… We apologize for the inconvenience, but the page you were trying to access is not at this address. You can use the links below to help you find what you are looking for. If you are certain you have the correct web address but are encountering an error, please contact the Site Administration. Thank you. But without the last language code part, https://extensions.libreoffice.org/templates works.
It works for me, please try again. It must have been some temporary glitch or live development experiment.
I confirm, but it should be reported to Redmine. https://redmine.documentfoundation.org/projects/infrastructure
