403 Error after Login (only main page)

Hello,

I've already read through all the topics which are relevant, but in my case it's a slightly more strange problem:

After the successful CB Login the entire website is accessible, except the main page (conna.eu). I get 403 Error.

Surprisingly, if I've logged in with www.conna.eu the error doesn't appear by adressing the non-www root page conna.eu and vice versa.


Joomla! 3.4.5
CB 2.0.12
PHP-Version 5.5.30

Does anybody have an idea or an approach?

Thx in advance,

Generally speaking you should not have 2 versions of your site for SEO-duplicate-content-penalty reasons. Ask your hoster how to redirect the non-www site to the same page on the www one (if that's your main one) (or if you self-host just adapt your htaccess file for that).

That said, this could be a mod_security issue. Check your Apache error log.
