Can anyone suggest what I ask my host to do to find out what the heck is going on with their servers. Every few days we get the page 'Internal server error - 500' and the local error logs for the domain shows nothing. The host claims the server is 'working fine' !
The scripts are all working ok as far as I can see, and have been working like so about 3 years without many changes apart from minor word changes to some files.
Is there some logger or something that they can use to find out anything as to why this error is showing up ?
