    Hey there, first of all thanks for this great plugin (even I didn’t had chance to try). I couldn’t install this plugin on my wp site which i am running on Windows server. I tried to install automatically from plugins. Whenever I change the wp-config file and add wp-cache defined thing whole my site (including admin-panel) becomes blank page’s. What might be the problem?

    (I have changed the names of folders ‘wp-content’ and ‘plugins’ directory when I installed wp. And because my server is windows server i cant use .htaccess file, i hve web.config for mod_rewrite)

    Thanks!

    btw, I also have tried installing super-cache manually, uploading it to ftp, changing the wp-config file and activating it.

    Check your PHP error log. A PHP error is the usual reason for what you’re seeing and it might give you a clue as to what is going wrong.

    Hi there, I woke up this morning and found my site returning a blank white screen. First thing I did was rename ‘wp-super-cache’ to ‘wp-super-cache-disabled’ and the website came back up. I don’t have any errors in ‘error_log’.

    I’ve been using WP Super Cache for a long time and it’s always worked. Recently, I made some modifications to my .htaccess

    I added these instructions:

    ExpiresActive On
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2 years"
ExpiresByType image/jpeg "access plus 2 years"
ExpiresByType image/png "access plus 2 years"
ExpiresByType text/css "access plus 2 years"
ExpiresByType text/javascript "access plus 2 years"
ExpiresByType application/x-javascript "access plus 2 years"
ExpiresByType image/ico "access plus 2 years"

    Also recently I installed WordPress SEO by Yoast.

    I’m thinking there might be a conflict between WP SEO and WP Super Cache, because the .htaccess instructions are used on another site as well without any problems, but WP SEO is only installed on the site where the white screen occurred.

    Anyway, these all are only guesses. I’d really like to know what the real source of this problem is. Please let me know how to debug this. I can’t find anything in ‘error_log’

    Thanks!

    I solved the problem by manually uninstalling WP Super Cache and then re-installing it.

    But I’d still like to know what caused that problem and is it going to happen again?!

    Same issue for me. Last night it was working fine, this morning a blank page. Nothing in error logs, manually uninstalled the plugin, removed the entries from htaccess & wp-config, deleted the two files in wp-content, and STILL there is no change…. blank page.

    I’ve been here several times in the past using this plugin, but restoring the site was always as easy as following the above steps…. however this has stumped me.

    Anything else I could be overlooking?

    Check your website for TimThumb vulnerability. I know someone who was hacked because of this vulnerability and his website was returning blank. Your problem may not be related to WP Super Cache.

    Found the issue. I made a change to functions.php when I was optimizing my clients cache/images/scripts. I restored a backed up version of functions.php… solved.

    Always a good idea to backup 🙂
