Wordpress: Internal Server Error

Question

I must move my wordpress website from one server to another. There is no way to backup it, so I copied wp-content files and moved to the new server. Also I moved database, so in my new server I have same database, same user, same password, also I changes user and password info in wp-config.php file.

But there is a problem such:

Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

and here is error log:

I really don't know what does it mean and how to fix it.

Thanks

The lack of a 5xx response code in your log file is interesting.

In the log extract you posted above, the last line is a request for /wp-admin.php , and is served with a 302 response code, which means it was redirected somewhere else.

I'm guessing this is happening because you configured the site to only allow users to log in over a secure (HTTPS) connection. So when you visit http://··(your site)··/wp-login.php , you're being redirected to https://··(your site)··/wp-login.php . If the new site doesn't have a proper SSL certificate installed, this will cause an error. (And it looks like your site is logging HTTPS traffic somewhere else.)

To prevent this from happening, edit /wp-config.php and change define('FORCE_SSL_LOGIN', true); to define('FORCE_SSL_LOGIN', false); .
