Log: Spinning Wheel

All I get when I go to Admin > Logs is a spinning wheel.

Ubuntu 16.04.2

NC is writing to the log.
I can read the log in CLI

a ls shows:

-rw-r----- 1 www-data www-data 159909 Mar 16 15:23 nextcloud.log

Any ideas?

Permissions seem correct. Did you try to adjust log level in config.php to i.e 4 to show less entries?

Log file doesn’t need to be executable, does it?

Updated to 11.0.3.
The wheel is still spinning.
No logs on display.
