[Linux] Every CMS: Object not found Error 404

[DonkerBonker6969]

So, this has been happening with every CMS that I have installed (Linux, Ubuntu 14 LTS). Everytime I install a CMS, either it goes to HTTP error 500 OR it redirects to

You must be registered for see links

instead of

You must be registered for see links

I have no idea how to fix these errors. Also I'd like to say that I prefer to use RevCMS (Which is currently installed) which gives me HTTP error 500

I hope someone can help me out, thanks in advance! Ps: I have set the permissions good
