Virtualmin Causing 500 server error with WHMCS

I dont know where else to put this. But it seems virtualmin does not do a gracefull reload of apache2? Causing an error after accounts are created using WHMCS. I have already been in communication with WHMCS and thats the story I get. and when I do try to do a gracefull reload in the CLI it throws error. Is there a fix for this?


What error do you see in $HOME/logs/error_log whenever receiving this 500 error?
