Has this been tested with multisite?
When running scan:
Fatal error: Maximum execution time of 45 seconds exceeded in /home/mysite/public_html/wp-content/plugins/timthumb-vulnerability-scanner/cg-tvs-filescanner.php on line 81
I tried to increase some of the timeout settings (Curl) in the plugin code to see if that would help, then ran again…seemed to run ok, but then seemed to finish with no indication of anything found or any other indication of anything. So I don't know if it worked or not.
I have a LOT of plugins installed (but not activated), so maybe that has something to do with it.
