has my server been hacked ?

[daniel69]

Hi I have some problems with my wordpress which lasts about 3 month:
Thanks to the error below(with some referrer from China) I have my Wordpress website once a day or 2 days down - 505 internal server error. To make my website run again I always need to delete .htaccess file . (btw.The way how to make my website run again(to delete .htaccess file) told me bluehost operator .)
Can anybody help me to explain what is wrong , has my website been hacked or what those errors means? What am i supposed to do now? I'm sure that foreign URLS is something that in my errors shouldn't be (I have about 30 same errors in one minute , always almost the same from this chinese forum:

[Sun May 23 03:40:59 2010] [error] [client 213.5.70.184] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so: cannot open shared object file: No such file or directory in Unknown on line 0, referer: http://forum.vipearn.com/thread-10523-1-1.html

Can anybody help me to explain how to eliminate this problem? Unfortunately im not PHP - Apache expert at all ,
I would be very happy if anybody can respond , Daniel

chances are those "foreign urls" you are seeing are in the main server error log. I am assuming that you are using shared hosting, which means that there are a lot of other websites on the same server as your site. If you scroll down in on the error screen you will be able to see errors related to your site with the heading of what directory of yours the errors come from...

what is the content of your .htaccess file that you keep on deleting?

Is vipearn.com your site? If not, that error is being generated by some other account on your server.

It is possible that i can see other logs?
I didn't know that , in fact i'm trying to find the answer all the day for this , vipearn.com is some very big forum in china which is hosted on bluehost (whois info) too so it should result that you are really right . I have never know that i can see in my cpanel other error logs , I started to think that they are those who hacked bluehost server and are killing my website-

working .htaccess is this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

after 505 internal server error changes to this :
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
s

it always adds an "s" after the code

Hi Bob thanks for your respond , I've already responded in another post , vipearn.com is not my site at all , and i didnt know that i can see other error logs in my cpanel .

I start to be totally confused with this 505 internal server error , I never thought that my site has been hacked until i saw these foreign urls , if you all are right I'm happy because it means that it is only my PHP ignorancy who hacked my site and I need to start to control my code , start to disable my plugins one by another like the people in other forums are advicing me .

Yes, the main error log displays errors generated by every site that's on your particular server.
