Homepage will load but every other page provides an Internal Server Error

Hi
My homepage will load but every other page provides an Internal Server Error. I have recently moved my site from a local server where it worked perfectly well to the web.

My Error Logs look like this…

I have replaced the files class-wp-hook.php and load.php with the same files from a clean download of WordPress. That hasn’t worked. I have no idea what to do now.

Can anyone help?

Thanks
