realtime graph not working after upgraded to 0.8.8b

[chenhsien]

I have just upgraded my cacti from 0.8.7c to 0.8.8b and noticed that the realtime graph is not working. When checking the http error logs, I notice this:

[error] [client 10.33.248.182] File does not exist: /var/www/html/plugins/realtime/plugins, referer: http://cacti01/plugins/realtime/graph_p ... aph_id=341

I did another upgrade on another server and I got the same issue.

[error] [client 10.33.248.182] File does not exist: /var/www/html/plugins/realtime/plugins, referer: http://cacti02/plugins/realtime/graph_p ... aph_id=401

there is an additional "plugins" on the path [ /var/www/html/plugins/realtime/plugins ]. I also noticed the similar error for thold

[error] [client 10.33.248.182] File does not exist: /var/www/html/plugins/thold/plugins, referer: http://cacti02/plugins/thold/thold_graph.php

I tried to look around the scripts but no luck
