You didn't tell us which websites are causing the issue. Is it only the one "transformersgame" site? If so, have you contacted the website owners to see if there's a problem with the site? (It looks like that's the case.)
Which browser are you using?
Scanned your computer for malware lately? If not, please do..
Likewise, which operating system do you have on the computer?
Since it mentions a Framework Error", do you have "NET Framework" installed and updated on the computer?
Hope this helps and let us know more.

I receive this message when trying to access a forum/website. This has only started happening in the last 2 - 3 days.
"Framework Error
Please check the Kohana documentation for information about the following error.
/system/libraries/drivers/Cache/File.php [26]:
The configured storage location, /var/www/transformersgame.com/application/cache/, is not writable.
Loaded in {execution_time} seconds, using {memory_usage} of memory. Generated by Kohana v{kohana_version}."
Any info on what this means and/or how to fix it is greatly appreciated.
