I was sort of having the same problem. I had a custom landing page that, after sign in would re-direct to the index page. After the 1.4.0 update I got the 404 error, page does not exist when I logged in from that custom landing page only.

So I realized the problem was somewhere in the custom landing page I created. I checked and checked and I eventually found what was wrong. My custom landing page had a slideshow on it. The 1.4.0 update somehow was in conflict with the j query code I had for the custom landing page slideshow.

I removed that code and experimented with a javascript slideshow code instead and it worked fine. Since then I have placed my index page as the direct landing page until I rebuild another custom landing page.

Don't know if that helps but it was the cause of my 404 error problem. Check your custom pages etc. if you have any and remove the codes and see what happens.

hi kurt

thanks for your answer but the truth is not understood very well the question is that since installing 1.4.0 oxwall I could not access my page "index".

understanding according to your error message comes from a custom code in index page but that page is as it comes by default and is only displayed when a visitor enters the main page, after logging in and can not go to it so that page has no custom modification,

if you want you can check to come to my page http://cucutavirtual.com/red

and see the home page but if you register and login. can no longer go to the index page so I could modify it in any way,

I think I may have to do with. htaccess but do not know much of this

if you can give me better information would be helpful.

thanks

how do I get past that to the main site to disable the splash page?

My entire site works great, fresh install, but

http://ugcgaming.us/index

Does anyone know the fix?

I would be forever grateful!

mod_rewrite is good to go.

The rest of the website runs fine.

All my other websites run with now problems. All on this same server.

It's just http://ugcgaming.us/index

I cleaned out the error log. Restarted Apache.

This is the only error showing up that looks to be related.

Thank you very much for your help.

I feel stupid for not doing that myself

Thanks to Negotiation: Discovered File(s) Matching Request: None Could Be Negotiated

I figured out the problem and have fixed it. 

Multiviews seemed to be the problem.

Thank you again very much.
