Hi,

every time I save the settings I get the following PHP warnings on top of the page:

PHP Warning: SimpleXMLElement::xpath(): Invalid predicate in /xxx/libraries/src/Form/Form.php on line 1645
PHP Warning: SimpleXMLElement::xpath(): xmlXPathEval: evaluation failed in /xxx/libraries/src/Form/Form.php on line 1645

However all seems to work OK as far I can see - I know I could swtich all php warnings off but I thought I mention it.

Running PHP 7.1.12 and Joomla 3.8.3

Kind regards

Johannes
