My Pages format were HTML (/thread-x.html).
I installed Google SEO plugin, 1-2 weeks ago, now in google webmaster tools I can find about 1000 pages as not found pages. (same previous pages with html format)

I have a question. How can I fix them ? need to do it ?


other question:
have anyone any problems with his site status in google in recent times? (I can not find my forum in search results. seems many sites owners have this problem)

/Excuse me for bad English/

You made a little fault in your meta tags.

<meta name="language" content="Perisan">

Should be:

<meta name="language" content="Persian">

Your website is slow and search engines don't like that either.
The theme that you are using is conciderd old and your XHTML is not valid. And neither is your CSS.

No wonder..

It is in my signature!

Just saw it, I just edited my post.

Are you sure my website is slow ?
How can I check that my XTHML is valid or not?

XHTML: http://validator.w3.org/
CSS: http://jigsaw.w3.org/css-validator/

Its slow to me, but I am from The Netherlands (Europe).

Thanks a lot but this validator show same results for this website but this website has not any problem!!
