Sitemap problems all of a sudden

[norku]

Just noticed the following errors in my vbseo sitemap reports. Everything was fine until the 9th and for the last three days none of the bots are showing any activity.

The following errors are reported:




Warning: array_keys() [function.array-keys]: The first argument should be an array in [path]/vbseo_sitemap/index.php on line 286

Warning: usort() [function.usort]: The argument should be an array in [path]/vbseo_sitemap/index.php on line 290

Warning: arsort() expects parameter 1 to be array, null given in [path]/vbseo_sitemap/index.php on line 293
