WordPress is a bulky platform which executes lot many database and PHP queries. It increases rapidly when you are using lot many plugins on your system. These queries will increase the page load time and server load on your hosting account which will cause CPU throttling or excessive usage of resources. To minimize the load time and queries, we use WP Super Cache plugin which is an awesome solution for these problems. It reduces the load time as well as it reduces the server load by noticeable amount. But sometimes, you wil see that the plug-in WP Super Cache is not working properly on your blog and it is not doing its work properly. Here is a list of problems you may face on WP Super Cache and solution to achieve super cache of your site properly.
Problem: Getting error message “WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed!” at the bottom of the page source of the site.
Solution: Go to your FTP account and download the file advanced-cache.php from wp-content. If you mahe moved your site from one server to another then you will have to change the path of the file wp-cache-phase1.php in the advanced-cache.php file. Open the downloaded file and there you can see two paths provided in the PHP file. Change those paths to the correct one on your server and then upload the file. You are done. Now you can reload the page and check he page source. There at the bottom of the page source, you can see WP Super Cache ran successfully.
Problem: WP Super Cache admin panel not opening properly or throwing error that everything is read only.
Solution: To let the WP Super Cache work properly, you will have to change the file permission of certain folders and files to 777. Here is the list of files and folders for which you need to change the file permission:
- wp-content ==> 777
- wp-content/cache ==> 777
- wp-content/wp-cache-config.php ==> 777

Do you have any solutions for the problem when the whole theme breaks when Super Cache is activated. I have such a problem that whenever I try to activate Super Cache when I open the site, only the HTML code appears in the browser instead of the real page
This usually does not happen, can you please send me the test site link where this is happening, so that I could digg into the issue (please do not post link here, use the contact form. Thank you.)
