Answered Website was running fine, now has 503 error front and back

In a bit of a bind with this one so really appreciate any help.

As far as I can tell the website had been working fine but is now showing a Error 503: Service Unavailable that is being produced from Modx. I get the same error front and back end.

The website was using friendly Urls (if it makes any difference) and have renamed the htaccess file just in case.

The only thing that I know has changed but can't see how it would cause this is that the domain name was transferred from another provider to the one I am hosting the webserver on?

I'm not sure how to diagnose the issue with just that error showing and not being able to get into the backend.

I haven't cleared the cache yet, but might give that a try.

The hosting works fine as I can browse successfully to an image in the root folder.

Many thanks. [ed. note: mflammia last edited this post 11 years, 2 months ago.]

BTW, If you rename the .htaccess file, you should also turn off FURLs in the modx_system_settings table in the DB, though I don't think that's your main problem.

Deleting all files in the core/cache directory and clearing your browser cache *and cookies* are definitely things to try.

Also, check all the paths and URLs in core/config/config.inc.php and the database credentials there.

Check the paths in the config.core.php files: (in modx root, manager, connectors, and setup/includes)

Another possibility is that the hosts file on your local computer is still pointing to the IP of the old site.
