When installing the W3 total cache plugin my website shows blank page. I checked the .htaccess. I also tried wp super cache plugin. This plugin also shows the same error when cache is enabled. Kindly help me to find a solution. Thanks in advance.

I pasted your code in my dev server and did not see any errors.

That said Error 500 indicates an Internal Server Error. If you look at your server logs (Apache and PHP), you'll be able to find the exact source. It could be anything from a parse error in PHP or an unavailable Apache module on your web host.

A few things you can do:

  1. The cache plugin could be clashing with another plugin you have installed. Try deactivating your plugins and leave the cache plugin activated. If it's working, then you have a plugin crash. Then you can slowly activate each plugin until you find the problem plugin. Remember, only use a plugin if it's absolutely necessary and it's something you can't solve in the theme development itself.

  2. Try removing that blank line before # END WordPress. .htaccess files can throw errors when whitespace is detected.

  3. Turn on WP_DEBUG in your wp-config file whilst developing, this can help you prevent any future errors like this.
