After upgrade I can not login trough web interface

After upgrade I can not login to server (nothing happens when I press login button). Nothing in logs only error in browsers console Screenshot%20from%202019-05-19%2000-32-44

Looks like I have the same problem. After update from 15.0.7 to 15.0.8 no login via browser possible! Nothing happens. How/what can we check?

PS: Access via mobile App is possible.

Got a similar problem with my cloud a few days ago. When updating from 15.0.7 to 16.0.1, it stopped login me on web side. My solution was changing, on the php config (etc/php7/apache/php.ini), the configuration for the maximum POST size

max_post_size = 10G


max_post_size = 10737418240

And then restart the apache web server

Also it worked with the max_post_size = 0, that means no limit. But it seems dangerous to me.

The clue was in a nextcloud.log file

{"reqId":"J43WZxopmIkYoieW4GvP","level":3,"time":"2019-06-06T10:25:22+00:00","remoteAddr":"","user":"--","app":"PHP","method":"POST","url":"\/index.php\/login","message":"Unknown: POST Content-Length of 197 bytes exceeds the limit of 10 bytes at Unknown#0","userAgent":"Mozilla\/5.0 (X11; Linux x86_64; rv:67.0) Gecko\/20100101 Firefox\/67.0","version":""}

The matter was the length of the POST, as php was interpreting that only 10 bytes where allowed
The original limit was 10 Giga, put as 10G
The G was never interpreted as Giga :upside_down_face:
