I've recently installed Cockpit CMS on Apache. Doing some customization on its UI. Everything was okay until I've changed its header icon then whenever I tried to save something on Collections, Forms, Singletons, or even adding entry, it says "File not found". I'm stuck in it.
I didn't touch any single code on its config and modules. Any help is much appreciated.
Here's my cockpit.conf:
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/cockpit
ServerName [My Server's IP]
ServerAlias www.example.com
<Directory /var/www/html/cockpit/>
Options FollowSymlinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory /var/www/html/cockpit/>
