 * Thank you offering this amazing plugin! Our team is currently preparing to upgrade
   our servers from PHP 7.4 to PHP 8.3. As part of this process, we conducted a 
   review of your plugin to check for PHP 8 compatibility.
 * During our investigation, we identified the two errors listed below. Would your
   team be able to look into these and advise whether they can be addressed in a
   future update?
 * Details are provided below:
 * FILE: core/admin-themes.php Line 188
 * Passing the $glue and $pieces parameters in reverse order to implode has been
   deprecated since PHP 7.4 and is removed since PHP 8.0; $glue should be the first
   parameter and $pieces the second
 * FILE: core/admin-extensions.php Line 187
 * Passing the $glue and $pieces parameters in reverse order to implode has been
   deprecated since PHP 7.4 and is removed since PHP 8.0; $glue should be the first
   parameter and $pieces the second
 * The fix should be straight forward, just need to swap the parameters so implode(
   wptouch_get_theme_features(), ‘, ‘ ); should be implode( ‘,’, wptouch_get_theme_features());
