Very strange problem

hi i am facing a strange
problem. Even not able to
expalain but let me try to
explain
i have word press installed
and in my dasboard some
links like update plugin
leads to 404 not found. I
was thinking it is related to
word press
now i installed phpbb and it
is showing same problem in
some admin area(in forum permission and board setting option) is there
any server problem.i also faced same problem with smf too.
My domain is
studentlife.co.in
and forum is /forums

 

You might be missing a .htaccess file. It should contain something like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Code (markup):

 

i have a .htaccess but to enhance site security and prevent dos attack i've added some filtering code. does this cause a problem

 

yes...modifing or adding .htaccess entries may even give u a 500 error sometimes....if you are unsure...then just rollback the changes u have made and add the change boltok told to the bottom of .htaccess file...save it...then if the problem persists either generate a new .htaccess file or contact your server administrator or tech support

 

now i am springed into new problem just because my current host tech support is not so good i decided to move another host, but due to some reason that move fails so i switched back and every thing goes ok, but just after some hour my site starts showing install of new host and my old site gone. Any idea

 

i am able to access site on pc but on my cell it is showing different content of new host which is not used by me

 

Maybe it is because you're phone and PC isn't using the same character encoding.

 

I'm not sure I follow you but if you're using two different internet connection for PC vs phone then your domain may not be fully propagated yet. If that's it, it will clear up soon.
