 * Hi,
 * Sometimes i can not access to the admin panel and get 500 internal server error.
   and most of the times it takes so long time to open the pages on admin panel.(
   there is no problem about the site speed).
    I asked this to my hosting company
   but they told there seems no issue about their systems.
 * I read some posts about the same issue and saw that this may be something related
   with .htacces file. I am using W3TC Browser Cache plugin and it added lots of
   rules to my htacces file:
 * # BEGIN EXPIRES
    <IfModule mod_expires.c> ExpiresActive On ExpiresDefault “access
   plus 10 days” ExpiresByType text/css “access plus 1 week” ExpiresByType text/
   plain “access plus 1 month” ExpiresByType image/gif “access plus 1 month” ExpiresByType
   image/png “access plus 1 month” ExpiresByType image/jpeg “access plus 1 month”
   ExpiresByType application/x-javascript “access plus 1 month” ExpiresByType application/
   javascript “access plus 1 week” ExpiresByType application/x-icon “access plus
   1 year” </IfModule> # END EXPIRES #Header unset ETag FileETag none

 * So the reason your site is fast on the front and slow on the back is probably
   due to you using a caching plugin.
 * W3TC is basically reducing the amount of calls to the database and a lot of the
   processing has to do, where as when you login as a admin, you are no longer seeing
   cached content and are seeing the site performance as it would be if you didn’t
   have total cache installed. To test this you can turn off total cache entirely
   then go in a different browser and see the entire site is slow (you probably 
   get a few 500 along the way)
 * Assuming this is the case, and also you don’t have control over the server, it’s
   a shared host then you may need to chat to your host about changing hosting plans
   or look at alternatives.
 * However it’s worth making sure you cover simple performance steps, like removing
   plugins you don’t need, you might also want to reduce post revisions down to 
   2 or 3 and look at cleaning and optimising your DB.
