I am getting this error on the homepage and the admin page after trying to install an extension that failed.
I have attempted the fixes on the other questions, but I am still getting the error.
I have searched the entire site for a maintenance.flag file but it doesn't exist. I have also deleted the session data and cache manually within FTP.
I am still getting this error. Any ideas as to why?

I think the compiler is enabled. Disable the compiler.
Go to:
System->Tools->Compilation
then disable the compilation.
