I just bought the plugins: Chained Fields k2 and MEFG. There is a conflict between them, when active MEFG plugin, the Chained does not work properly. I ask you to check this please conflict.
Does each plugin work alone, but Chained Fields does not work when MEFG is enabled?
If yes, can you check for any javascript errors?
If no javascript errors, it can be a time delay issue, so please use firebug or a similar tool to check for the response time of each plugin.
if you can send a screenshot of the console tab this will be very helpful.
