I have WP site,but I have problem in wp-admin then I edit post i see there my ref links but then I save it and logout to watch in user mode I see in every my ref links this:

mysite.com/-WP- Post-/forbidden

Click to expand...

I using this plugins:
Akismet ,Easy Privacy Policy, Google XML Sitemaps,Limit Login Attempts,SEO Plugin by SQUIRRLY,Short URL for Posts and WordPress SEO

it's hard to answer like this, does it also show some kind of error code

This issue happened because of server over load. I think you need to contact the server.

try deactivating plugins one by one and you will find out which one is creating the problem.
