# Enabling caching causes 500 error

 * Our clients website is running very slowly and the server keeps crashing daily
   so I thought I would try installing cache plugins such as W3 Total Cache to speed
   up the page load, but it just caused a 500 internal server error.
 * I had to then manually remove the plugin and any links/files/code it had created.
   I then tried the .htaccess caching and it brought up the same error.
 * Why is caching causing my site to crash and is there any way to fix this? (granito.
   co.id)
 * Any guidance would be great as this issue is causing the client to lose in google
   ranking.
 * Thanks

 * Thanks for the feedback but its not the solution I was looking for. Its not just
   the W3 Total Cache plugin that causes the 500 error but any changes to the .htaccess
   file in relation to cache.
 * This is the code I added to the .htaccess file
 * ## EXPIRES CACHING ##
    <IfModule mod_expires.c> ExpiresActive On ExpiresByType
   image/jpg “access 1 year” ExpiresByType image/jpeg “access 1 year” ExpiresByType
   image/gif “access 1 year” ExpiresByType image/png “access 1 year” ExpiresByType
   text/css “access 1 month” ExpiresByType text/html “access 1 month” ExpiresByType
   application/pdf “access 1 month” ExpiresByType text/x-javascript “access 1 month”
   ExpiresByType application/x-shockwave-flash “access 1 month” ExpiresByType image/
   x-icon “access 1 year” ExpiresDefault “access 1 month” </IfModule> ## EXPIRES

 * I want to be able to speed up the site without it giving me a 500 error everytime.
   Do you have any idea why I am receiving this error?

 * – Your first step should be checking your site’s error logs for a more specific
   error message. If you need help locating them, ask your hosting provider to help
   you with that.

 * I do not have access to the error log so will ask my provider and update you.
   Thanks

 * Also discuss the error with the provider if logs show any specific error,

 * The host sent me the log.txt file. I don’t think this is the error log though
   as I cannot find anywhere were it says an error occurred.
