FCG and Arnan de Gans' Events and Ad Rotate

[prosperewebitor]

I asked this question in another thread, but didn't get an answer (apologies if I'm breaking any rules), but does anyone know if these conflict with FCG? The reason why I'm asking is because I TRIED deactivating the plugins, but got an error page (with a note saying there's an internal server error). I'd like to figure out if it's a plugin issue or a coding issue.

Thanks
