# warning: Invalid argument supplied for foreach()

I apologize if this is in the wrong area, I'm not sure where it goes. Can anyone help with this issue I've been encountering, I'm unable to view "Recent Log Entries:" and always get the follow warnings:

# warning: Invalid argument supplied for foreach() in /home/xx/public_html/includes/common.inc on line 884.

# warning: strtr() [function.strtr]: The second argument is not an array in /home/xx/public_html/includes/common.inc on line 901.

When I opened the file in an editor, this is what both lines show:

line 884: foreach ($args as $key => $value) {

line 901: return strtr($string, $args);

Any clue to what I should do so that I can view my log entries? Thanks in advance.
