VBSEO errors in error log

Since installing VBSEO today, I'm getting a LOT of error messages in my CPANEL error log.....can anyone tell me what might be causing these?:

Code:

[error] [client 207.200.116.136] File does not exist:/home/******/public_html/forums/clientscript/vbulletin_css/style-4e289eff-00024.css
[error] [client 69.162.154.13] File does not exist: /home/******/public_html/forums/clientscript/vbulletin_css/style-3780548c-00024.css
[error] [client 209.88.21.195] File does not exist: /home/******/public_html/forums/clientscript/vbulletin_css/style-0614d2a6-00024.css

Hello Rich,

are these files existing? They are probably old css files created by vBulletin when style settings are changed and are still accessed, for instance, when viewing cached page in Google search results.

Hi,

It could also be that you set the CSS to be stored in the filesystem but did not chmod 777 the vbulletin_css directory. Change the permissions and you should resolve this.

yeah, the css files are stored in a file /public_html/forums/clientscript/vbulletin_css, and its chmodded to 777
Is this not a good way to run things? Should i set it back to the default?

Having CSS in files like that is the better way to go. It cuts down on the amount of code in your pages. Those errors will come up from time to time when you make changes to your style and it has to generate a new CSS file. If users have old pages cached, and try to hit them, it will look for the previous CSS filename.

cool beans....thanks
