Interne Serverfout after one click update Hello and good evening,

After the one click update the message 'Interne Serverfout' appears on the screen. One can no longer connect to either the fron or backend of the installation ? 

What is the correct procedure to roll back to a working website here ?

Interne Serverfout (Internal Server Error) is a fatal error that has happened and your web server killed the request.

Usually, fatal errors like this are either because PHP times out, or runs out of memory... the underlying error message will be either in your web server's error logs or Craft error logs.

Try editing your php.ini file and increasing the memory_limit setting to at least 256M, and the max_execution_time setting to at least 120.

If you’re not sure where your php.ini file is located, create a PHP file called ini.php alongside your index.php file with this:

php
echo 'Loaded php.ini: ' . php_ini_loaded_file();


Then access that file in your web browser by going to http://your-project.test/ini.php.

Once you’ve made your changes, restart your web server, restore your database from a pre-update attempt database backup and then try again.
