# WP Super Cache causing 'Internal Server Error"

 * I’ve been running the WP Super Cache (v. 0.9.9.9) for the last couple of days
   in my WordPress (v. 3.1) site, and it was seemingly working fine. However, this
   morning my site began to sporadically show:
 * “Internal Server Error
    The server encountered an internal error or misconfiguration
   and was unable to complete your request.”
 * After a little research, I found this problem was linked to WP Super Cache, so
   I began testing it and checking its logs. Sure enough WP Super Cache seems to
   be showing issues, but I’m not sure what the fix is. When I go to the plugin’s
   settings and “test cache”, it shows that it is able to fetch the first and second
   copy, but shows that “One or more page requests failed” and lists:
    Page 1: 500(
   Internal Server Error) Page 2: 500 (Internal Server Error)
 * The logs show a continual repeat of the following scenario:
    13:51:00 /wp-login.
   php?redirect_to=http%3A%2F%2Finthenameofgadd.com%2Fwp-admin%2F&reauth=1 URI rejected.
   Not Caching 13:52:53 / Created output buffer 13:52:54 / Output buffer callback
   13:52:54 / wp_cache_shutdown_callback: collecting meta data.
 * I am using “mod_rewrite” to serve cache files, and I have unchecked “compress
   pages”, as that seemed to give one user issues, but has not fixed my problem.
   I have enabled CDN support, and I am also using the “cdn sync” plugin.
 * Can anyone help? I’ve seen that Donncha weighs in on these forums, hopefully 
   you can give me a hand?

 * One other thing: If I log into my site’s admin, that seems to fix it. I can access
   my site after that. But if I try to open the site from a browser or another computer
   that has not logged in to the WordPress admin, I run into the Internal Server
   Error.

 * I apologize for the multiple posts, but I’m finding things as I go. When I look
   in my site’s wp-content/cache folder, there are correctly rendered versions of
   my homepage there, but they are given filenames like: wp-cache-d996df6f9f4fa55761b95a1355534224.
   html, and the browser is pointing to 1.html, which gives the server error.

 * Just saw your last post, glad you got it working again. Broken .htaccess file?
   Unfortunately that’s easy to happen 🙁

 * Yeah, it is working now. I went into the settings, hit ‘view rewrite rules’, 
   noticed that there was a minor difference from what the htaccess file in the 
   cache folder was showing, and replaced the file with what the plugin was telling
   me should be there. Everything has been working since. Thanks for checking into
   it!
