Button 'in cart' not working anymore

Question

I found out that clicking on "in cart" button on a product page is not working anymore. (www.deli-discountnl) while on the overview page when you click on the basket it still works. And I am having a system.log of 500 mb!?

This is the first line:

2016-10-10T10:16:37+02:00 ERR (3): Warning: simplexml_load_string(): Entity: line 96: parser error : StartTag: invalid element name in lib/Varien/Simplexml/Config.php on line 383 2016-10-10T10:16:37+02:00 ERR (3): Warning: simplexml_load_string(): ><sortorder/><location_picker>0</location_picker></dhlforyou_1456932693927_927>< in lib/Varien/Simplexml/Config.php on line 383 2016-10-10T10:16:37+02:00 ERR (3): Warning: simplexml_load_string():
^ in lib/Varien/Simplexml/Config.php on line 383

This is line 383 of the config.php:

$xml = simplexml_load_string($xmlString, $this->_elementClass);

What is going wrong here? Even more important, how can I fix it?

It is a multistore and with the other site (different template) www.vizenco.nl and www.bakmina.nl there is no problem.

Answer 1

search in your magento *.xml files for string ><sortorder/><location_picker>0</location_picker></dhlforyou_1456932693927_927>< (in app/code directory), seems it's just syntax error in xml file

pS: Better way to search for </dhlforyou_1456932693927_927>, because xml can xml may be with \n symbols (new line)
