How do I get ride of the black screen on updating my HML5 app?

Hi,

I already searched the forums and the manual,... but I did not find anything about this problem:

When I update my app and upload the new files, sometimes (not always) the app stops working. I only get a black screen.

I've already tried so many things but still the same. (server cache, browser cache, different splash screens, etc.)

On Ms Edge, after about 15 minutes or so, sometimes it comes alive again (refreshing the browser) but on Google Chrome, no.

Can anyone help me with this?

Thanks in advance.

Try pressing F12 and check for any errors in the browser console.

You might want to check your server cache settings as well - it's possible the server is serving mixed content (i.e. some files from an old version, and some files from the new version) which would likely break things. You should make sure there isn't some caching setup that might do that.
