Logdateformat not working

Hello all,

for the past days I’ve been trying to modify the way the time shows in the logging section of nextcloud.

currently shows as 2013-01-10T15:20:25+02:00 and would like to show something like January 10, 2013 15:20:25

now, I’ve been trying to change this on the config.pho by adding the following line:
‘logdateformat’ => ‘F d, Y H:i:s’,

when i refresh the page, it keeps on loading not showing anything.

if i remove that line from the config.php and reload the page i get the log back with error:
Error: Call to a member function format() on boolean

can someone please help me out on trying to get this properly setup?

im running on version 11.0.3
Apache 2.4.25

thanks a lot for your insights
