just found the time to follow all the suggestions on of the warnings that are listed on the general tab of my settings page.
I managed to configure the opcache, install redis and APCU ( or ACPU , dont remember ) and i fixed the non-finished indexes.
After that i was curious and clicked on the “security-scan my system” link.
I got a bad rating : E because the scanner did not correctly identify my installed version of nextcloud -> 14.04
The scanner tells my my installed version is : 220.127.116.11
Is that a known bug?
Am i doing something wrong?
The only thread i found about this is more than a year old and it doesnt reveal a solution.
Any further help is appreciated.
