Updating website icon in Joomla 5

Posted by | Joomla |

For the Cassiopeia template, Joomla will look for the favicons in the following locations:

  1. media/templates/site/cassiopeia/images – they are not there so Joomla will look in the next location.
  2. media/system/images – they are there so Joomla will use them from there.
wget -O - https://sharlines.com | grep -i favicon

        <link href="/media/system/images/joomla-favicon.svg" rel="icon" type="image/svg+xml">
        <link href="/media/templates/site/cassiopeia/images/favicon.ico" rel="alternate icon" type="image/vnd.microsoft.icon">
        <link href="/media/system/images/joomla-favicon-pinned.svg" rel="mask-icon" color="#000">

How to update a WordPress website securely

Posted by | WordPress |

To prevent a website from changing its source code set user = nobody in its pool config, that can be /etc/php/8.3/fpm/pool.d/slogpost.conf for example:

[slogpost]

user = nobody
group = slogpost

listen = /run/php/www-slogpost.sock
include=/etc/php/8.3/fpm/socket-owner.conf

pm = ondemand

pm.max_children = 10
pm.start_servers = 0
