Seo url troubles on localhost

[mgrc]

When building your site in a subfolder on localhost, what must be changed for seo url to work properly?
Everything else works fine.

[Mr.HeLL]

open .htaccess

change

RewriteBase /foldername/

[mgrc]

Tried that. Front seems to work, but in admin area links stop working (only main admin page is working).

LATER EDIT

Thanks, your suggestion is correct,
I have previously messed with RewriteRule for admin folder in .htaccess but forgot to remove changes.
I was confused as other sites work fine.
