Error message on the CMS (1.7.2)

While checking the logs from the CMS for another issue, I notice we get an error message several times per minute:
<errormsg>Invalid argument supplied for foreach()</errormsg>
<errornum>2</errornum>
<errortype>Warning</errortype>
<scriptname>/var/www/xibo/lib/service/xmdssoap4.class.php</scriptname>
<scriptlinenum>426</scriptlinenum>

What is going on here? Any help welcome.

Grtz,

Very likely it’s an old client returning stats or logs in an invalid format.

You should upgrade both Players and CMS to the latest 1.7 or 1.8 releases. 1.7.2 is very old now. 1.7.11 is the latest 1.7 release.
