past many days i am facing 500 internal error whenever i try to open it. because of it my forum/wordpress/sftp/ssh is down
website is working. database is created in kloxo panel hence database related all services are down.
mostly i upload via ftp but now facing trouble. BLUEVM support staff is of no help[ the were never a help]
i submit the ticket but no solution was made and now no reply . at their IRC they boast of help but i never found any help.
moreover they don't accept any responsibility.
please provide me suggestion/advice and expertise knowledge to overcome this problem
