When moving my website from PHP 7.x to 8.x, the CodeColorer plugin that I use, started crashing saying that "create_function() is deprecated" (see also PHP manual where I also found how to make a fix for this issue). Thank goodness, the fix wasn't super difficult.

In this file

/wp-content/plugins/codecolorer/geshi.php

Goto line 4697 and look at the "if" statement.

if (!isset($callback_2)) {
  $callback_2 = create_function('$matches', 'return "[" . str_replace("|", "", $matches[1]) . "]";');
}

which I changed (line 4698) to:

if (!isset($callback_2)) {
  // old: $callback_2 = create_function('$matches', 'return "[" . str_replace("|", "", $matches[1]) . "]";');
  $callback_2 = function($matches) { return "[" . str_replace("|", "", $matches[1]) . "]"; };
}

For me the plugin now works as before.
