Im trying to access my admin section at site.com/administrator/index.php and all it loads is my frontend homepage. I've already deleted my cache. So how do I fix this and will this be a reoccurring issue?

Are you sure "administrator" is correct path?
Default install points to "admin", therefore if you did not change admin directory name and $config['admin_dir'] setting in config.php maybe you are simply trying to access wrong URL.
If you did change it, then it may be a issue with some .htaccess redirect.
