I have now got it working. I didn’t come across those instructions once when searching – only the old document.
However, there is an error in the new document. In it you state “replace en_US in the file name with en_UK, es_ES, fr_FR, etc, if necessary” but for UK it’s en_GB.

Thank you.
Managed to achieve it by using an iframe

My code isn’t in WordPress so can’t use LiteSpeed_Cache_API::purge($tag)

Also have a problem with using header(“X-LiteSpeed-Purge: /your-php.php”) as I get Cannot modify header information – headers already sent by etc

To explain better I have a php file that contains a form which posts back to itself. On submitting, the form fields are used to run query to update database. Once query has run I then want to purge the corresponding page and then redisplay form with fields populated with database values.

I’ve checked and double checked with hosting company and memory limit is set to 1024M so don’t think this is the problem.

Any other ideas as to what might be causing this?

Thanks Nick, that set me on the right path and I now have it working as wanted.
For anyone else wanting to resize images after upload this is what I ended up with.

if (!function_exists('wfu_before_file_upload_handler')) {
    function wfu_before_file_upload_handler($file_path, $file_unique_id) {
      $_SESSION['wfu_tempfiles'][$file_unique_id] = $file_path;
      return $file_path;
  }
  add_filter('wfu_before_file_upload', 'wfu_before_file_upload_handler', 10, 2);
}
if (!function_exists('wfu_after_file_upload_handler')) {
  function wfu_after_file_upload_handler($changable_data, $additional_data) {
	$file_unique_id = $additional_data["file_unique_id"];
    if ($additional_data['upload_result'] == 'success' && isset($_SESSION['wfu_tempfiles'][$file_unique_id]) && $_SESSION['wfu_tempfiles'][$file_unique_id] != '') {
     $filepath= $_SESSION['wfu_tempfiles'][$file_unique_id];
	 //now that we have the path to uploaded file we can resize it using our resizeImage function in our functions.php file
	 resizeImage($filepath, $filepath, 600, 600);

	}
	return $changable_data;
  }
  add_filter('wfu_after_file_upload', 'wfu_after_file_upload_handler', 10, 2);
}
