PHP Error

Hi, I happened to be poking around in my error logs for some reason today and I noticed I am getting a PHP error multiple times related to SEO Ultimate.

Here is the specific error:

PHP Warning: uasort() [function.uasort]: Array was modified by the user comparison function in /home/username/public_html/wp-content/plugins/seo-ultimate/plugin/class.seo-ultimate.php on line 550

It doesn’t look like it happens all the time, but when it is happening it logs a bunch in 1 day. There’s probably about 200-300 of them all in a row over the course of a year…this is the 1st time I’ve checked my error logs.

The last ones were logged on April 17th.

Anything to worry about?

Thanks.
