This is second time this happening to me. The login screen is empty with no user name and password input boxes. I can no login to web interface. From my phone I can still access my mail and everything but not from the browser.

I did backup everything and try to fresh installed but it is still like that. I have no idea what happened. I did not change anything. I did try to go down with PHP version on my host but that did not do anything. Please help, what I can try?

Tnx

One of the possible reasons of this is Content-Security-Policy feature. If you press F12 in the browser and check Console, you might see an error message related to this feature.

Try setting ContentSecurityPolicy value to empty string in data/settings/modules/CoreWebclient.config.json file or, if you run version prior to 8.5.3, in data/settings/config.json file.

If this doesn't help, see if you get any other error messages in browser console. Also, enable WebMail logging by setting EnableLogging to true in data/settings/config.json file, reproduce the problem, check the logs under data/logs/ directory and see if any errors are recorded there. You can send us the logs for examination via HelpDesk.

Also, instead of disabling CSP entirely, try setting ContentSecurityPolicy to the following value:

Code:
default-src 'self' 'unsafe-inline' 'unsafe-eval' blob: ajax.cloudflare.com; img-src * data: blob:; frame-src *; font-src 'self' data:


or

Code:
default-src 'self' 'unsafe-inline' 'unsafe-eval' blob: cloudflare.com; img-src * data: blob:; frame-src *; font-src 'self' data:


and let us know if either of those worked for you. Thank you.

Oh thank you so much. Replacing CSP with first value worked. I can normally login in my browser now and all is back to normal.
