if you didn't changed files or uploading. You can revert back to your previous copy of mysql database (which is working).

if you uploaded physical files, you might need to reupload. Might be due to bad files caused by ftp error too.

It can be caused by many reason.
- make sure the wordpress plugin is supported. You can rename the "plugin" folder and refresh your site. If its working now, this mean some of the plugin is causing the error 500.

- make sure the .htaccess is configure/edited correctly. Upload to server too.
