Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

{literal}
{literal} tags allow a block of data to be taken literally. This is
typically used around Javascript or stylesheet blocks where {curly
braces} would interfere with the template
delimiter syntax. Anything within
{literal}{/literal} tags is not interpreted, but displayed as-is. If
you need template tags embedded in a {literal} block, consider using
{ldelim}{rdelim} to escape the individual
delimiters instead.
Note
{literal}{/literal}tags are normally not necessary, as Smarty ignores delimiters that are surrounded by whitespace. Be sure your javascript and CSS curly braces are surrounded by whitespace. This is new behavior to Smarty 3.
<script>
// the following braces are ignored by Smarty
// since they are surrounded by whitespace
function myFoo {
alert('Foo!');
}
// this one will need literal escapement
{literal}
function myBar {alert('Bar!');}
{/literal}
</script>
