Web visualization is not working after updating the NETx server

If you update to a new version of our software, it may be the case that the web visualization is not working correctly. E.g. button states are not shown correctly, button clicks do not work, or other suspicious behavior during the usage of the visualization.

The reason is that the web resources (JavaScript, HTML and CSS files) may be changed during the update. The web browser has still the old version in the cache and uses them for presenting the visualization. Since these old cached files do not match with the files that is expected by our web server, problems occur.

To solve this issue, the web browser caches must be cleared at the clients i.e. at all stations where the web visualization is used.

In Chrome this can be done by pressing F12 (this will open the developer console), right-click at the reload button and selecting “Empty Cache and Hard Reload” (in German “Cache leeren und vollständig aktualisieren”).

Open

In other web browsers, this is done similar.
