I honestly don’t know what would cause that as it’s not code in the plugin. It’s apply_filters() which should be fairly robust. Does it go away if you install 0.9.9.3 again? * Thread Starter [dynamick](https://wordpress.org/support/users/dynamick/) * (@dynamick) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688025) * Yes, I’ve restored the old 0.9.9.3 and now all it works. * Hope you could fix the problem.

The home and the admin works normally. * Any ideas? Perhaps some other plugin could corrupt somethings… * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688242) * dynamick – You could try dumping all the variables used on line 166 of wp-includes/ plugin.php * Dump them to a log file with error_log( print_r( $variable, 1 ) ); and they’ll appear in your error log. That will tell us what error created the WP_Error. * Thread Starter [dynamick](https://wordpress.org/support/users/dynamick/) * (@dynamick) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688248) * um… it is too difficult to dump that variables. I’ve tried but I’ve got too many visitor traffic, and the php log is full of waste. * Now I try to transfer the site to a private host, so I could analyze and post the log. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688253) * Limit it to you IP address using $_SERVER[ ‘REMOTE_ADDR’ ] and you should get a small log! Thanks, I appreciate the trouble you’re going to helping me fix this. * You could also use if ( is_wp_error($variable) ) to limit the dump to those filters that actually are errors. * [Green](https://wordpress.org/support/users/hambone614/) * (@hambone614) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688255) * Having the exact same issue. trying to uninstall via the directions. I am a very non-tech savvy person, so getting through this is a pain. been at it for an hour and cannot get this thing uninstalled. Will post back with more info once I am able to uninstall and reinstall older version. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688256) * hambone614 – use your ftp client to download and edit your wp-config.php and remove the line that mentions WP_CACHE. Upload again and your site will be fine. * [Green](https://wordpress.org/support/users/hambone614/) * (@hambone614) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688257) * just got it uninstalled and re-installed older version. receiving error: * Fatal error: Unsupported operand types in /home/MYSITE/public_html/wp-content/ plugins/wp-super-cache/wp-cache.php on line 621 * My pages and posts are still receiving error as well. What should I do? * Thank you in advance for your patience, much appreciated Donncha 🙂 * [Green](https://wordpress.org/support/users/hambone614/) * (@hambone614) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688258) * Oh, and the line that mentions WP-CACHE was removed when I uninstalled the new version. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688259) * Try cancelling the preload or starting it again. The new version of Supercache changed the “preload_counter” format to include a timestamp so it could restart stalled preloads. * [Green](https://wordpress.org/support/users/hambone614/) * (@hambone614) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688260) * Only half caching works. When I turn on full caching, I get the error I stated above directly under the preload cache section. * Sorry to be pushy, I just made page 1 for 3 search terms, each with 400 million competing +. What info can I give you to resolve this as quickly as possible? * [Green](https://wordpress.org/support/users/hambone614/) * (@hambone614) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-blank-page/#post-1688261) * Even after uninstalling, my pages and posts were still blank. I then reinstalled and it remains the same. Don’t know if that helps at all.
