update-php类导致500内部服务器错误

Question

update -now apache is not giving any error. i have seen this earlier also. 99% times it will throw error 500 .see this screenshot. it shows no error at all.

i dont know how to solve this problem. it will again start showing after sometimes

i have created one page which seems to be normal page when we open but in chrome and mozilla it gives error.

      Failed to load resource: the server responded with a status of 500 (Internal Server Error) 

http://imgur.com/a/macb7
page is http://xxxxxx.com/mobile-under-10000

and i have found that if i change the name of link to http://xxxxxxx.com/mobile and add class it gives no error.i cant add php class in mobile-under-10000 as class will not allow - but i really need that name as its seo friendly. if i create pages like this it works but i have to choose only one word in classname. i have thousands of links which is working fine but giving 500 error.

<?php
class samplelink {
    function index() {
echo 'write something';
    }
}
?>

any idea to resolve will be great. i have one option to force apache to stop throwing 500 error.but it is advisable ? i am using nginx with apache.

please advise

my .htaccess code is

RewriteEngine on
RewriteCond ${LeechProtect:/home/xxxxxx/public_html:%{REMOTE_USER}:%{REMOTE_ADDR}:10} leech
RewriteRule .* http://xxxxxx.com
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^([0-9a-z_/\-]+)/$ index.php\?p=$1 [QSA]
RewriteRule ^([0-9a-z_/\-]+)$ index.php\?p=$1 [QSA]
</IfModule>


RewriteRule ^.* - [F,L]
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.xxxxx\.com$ [NC]
RewriteRule ^.*$ http://xxxxxx.com%{REQUEST_URI} [R=301,L]

If your Apache, and PHP / MySQL error logs are empty then there's a very strong likelyhood the issue is caused by .htaccess / httpd.conf so check these files for inconsistencies.

and i have found that if i change the name of link to http://way2enjoy.com/mobile and add class it gives no error

This strongly indicates that you have not properly escaped characters in your .htaccess .

EDIT

These lines:

 RewriteRule ^([0-9a-z_/\\-]+)/$ index.php\\?p=$1 [QSA] RewriteRule ^([0-9a-z_/\\-]+)$ index.php\\?p=$1 [QSA] 

Can be rewritten and fully escaped as :

RewriteRule ^([0-9a-z_\/\-]+)/?$ index.php\?p=$1 [QSA]

There are some curious behaviours that are in your htaccess but nothing jumps out at me as potential fatal issues.

Some points:

• You state reWriteEngine On three times in your htaccess, this may cause an error and so you can remove two times.

I have re-organise your code so :

 <IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteRule ^([0-9a-z_\/\-]+)/?$ index.php\?p=$1 [QSA]

 RewriteCond ${LeechProtect:/home/xxxxxx/public_html:%{REMOTE_USER}:%{REMOTE_ADDR}:10} leech
 RewriteRule .* http://xxxxxx.com

 RewriteCond %{HTTP_HOST} ^www\.xxxxx\.com$ [NC]
 RewriteRule ^.*$ http://xxxxxx.com%{REQUEST_URI} [R=301,L]
 </IfModule>

 RewriteRule ^.* - [F,L]

The final line returns a Forbidden header result (403) if it is ever reached, which seems to be quite heavy handed and possibly unnessecary response.

I also question the leechProtect statement but don't know enough about it to advise further. But use the code above and then check your site commenting out ( #comment ) each line and then clearing your browser cache (each time, as browsers cache htaccess rules) and see if commenting out some of these requests causes the site not to return 500 errors.

Good luck.
