Error Message in Log Files

This is causing apache errors, requiring the webserver to be stopped and started...leastways, I'm assuming it's this !

PHP Warning: file_exists() [<a href='function.file-exists'>function.file-exists</a>]: open_basedir restriction in effect. File(../http://www.**.co/) is not within the allowed path(s): (/home/httpd/vhosts//**.co./httpdocs:/tmp) in /home/httpd/vhosts/**.co./httpdocs/vbseo.php on line 71

Not aware of anything being changed, and certainly not to the plugin...

Please try to modify vbseo.php file:
FIND:

PHP Code:

if(!@file_exists($vbseo_relpath)) 


REPLACE WITH:

PHP Code:

if($vbseo_relpath && !file_exists($vbseo_relpath)) 


Thanks Oleg - have replaced the line, will check the log files over the next wee while.
