/public_html/wordpress/wp-content/plugins/fv-code-highlighter/classes/Cache.php
The fix:
Edit the file wordpress/wp-content/plugins/fv-code-highlighter/classes/Cache.php and add something like:
$this->setCacheDir( realpath($cacheDir) . ‘/home/linuxpro/public_html/wordpress/wp-content/plugins/fv-code-highlighter/cache’ );
Save, close, refresh and you are good to go. Good Luck.
