Hi!

I checked my site on this service (redirect-checker.org) and got an error

Result
https://mysitename.com
302 Found
https://mysitename/de/
200 OK

Problems found:
You use a 302 redirect. This means, that the actually content is temporary not reachable and will come back soon. To use a 302 redirection for generally moved pages is a bad idea. Search engine bot might not follow it or handle it as temporary. For SEO this is also a bad idea, because no link juice will be transferred to the linked page.
vBulletin 4.1.4, vBet 4.9.1
vBET - Language Detection - Always trust user

I ask for your help in solving this error.
