Hi Emre,
I have the same problem. I Deleted the old plugin and downloaded it again, with the same error…
Plugin could not be activated because it triggered a fatal error.
Warning: include_once(inc/common.php): failed to open stream: No such file or directory in /.../html/wp-content/plugins/wp-fastest-cache/wpFastestCache.php on line 24 Warning: include_once(): Failed opening 'inc/common.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /.../html/wp-content/plugins/wp-fastest-cache/wpFastestCache.php on line 24 Fatal error: Class 'WpFastestCache' not found in /.../html/wp-content/plugins/wp-fastest-cache/wpFastestCache.php on line 26
