today I bought «J51_Skylar» and installed my new website using the demoInstaller. Ok so far. The first thing I did in the back-end was upgrading from Joomla 3.9.18 to 3.9.19. This was ok as well. But now, an extension called «J51 Progress» is notifying me
J51 Progress Site Modul 1.0.0 1.1.0 Unbekannt Aktualisierung https://www.joomla51.com/updates/mod_j51progress.xml
https://joomla51.com/joomla-extensions/progress-module
When I select «J51 Progress» and click [Update] the screen becomes blank. The update can obviously not be installed. I need to clikc the browser's [Back] button in order to return to the backend.
Thank you and kind regards
Chris
