Possible issues with webservice because of the URL in the webservice

We have received a number of issues where the vacancies have disappeared from the website.
This most likely has to do with an URL that has EMEA instead of Instance reference in the URL:
<soap:address location="https://emea.salesforce.com/services/Soap/class/cxsrec/cxsPositionWebservice"/>
In order to fix this, change the EMEA part into your org instance.  

How to find your instance please read here.
