need help with SP supercache plugin

Edit: Sorry, title is misspelled, I mean WP Super Cache.

I have recently installed WP Super Cache on some sites of mine.

There is an option in there to do the caching with Mod_rewrite as opposed to PHP. (And this is where my subject matter knowledge drops off precipitously...)

If you choose mod_rewrite, it offers to update your whole .htaccess.

With all the new stuff in this .htaccess file, once in a while when I go to the site it only shows a bunch of gibberish on the front page and nothing else.

The link to login as a WP admin still works, though, and once I log in, the site goes back to normal.

Does anybody know what is going on, or how to fix it? Presumably it's in conflict with something else?

If it's possible, I would like to keep this plugin. It certainly makes a difference in the loading time of my site.

Thanks!

  • Use PHP. Also, if your webhost uses CloudFlare - I'd suggest using it.

    Would you mind posting what you see on the page when the problem occurs? Without knowing what's in the .htaccess file it's hard to troubleshoot...

    • What the plugin adds to the original .htaccess file is:
      # BEGIN WPSuperCache
      <IfModule mod_rewrite.c>
      RewriteEngine On
      RewriteBase /
      #If you serve pages from behind a proxy you may want to change 'RewriteCond %{HTTPS} on' to something more sensible

  • Good grief. Turn the mod-rewrite off and use PHP. What do you get then?
  • Good grief is right!

    all back to normal with the PHP option, also I rewrote my .htaccess to the original plain 5-lines or so.

    The site just feels faster with that more troublesome option, just trying to make it work, that's all, if anybody had any insight into that code.
  • Also,

    The more lines that have to be processed in the htaccess, the slower the site will be. The htaccess file gets processed before serving any data.

    My suggestion - use a CDN such as CloudFlare. We recommend this to all of our customers and we use it on our site. CloudFlare in combination with LiteSpeed (replaces apache) is amazing.
