Title: Warning: include_once(): WP Super Cache error Last modified: December 10, 2019 --- # Warning: include_once(): WP Super Cache error * [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/) * Getting the following errors at the top of my page (pdximmigration.com): * Warning: include_once(/home3/[myaccountname]/public_html/wp-content/plugins/wp- super-cache/wp-cache-phase1.php) failed to open stream: No such file or directory in /home3/[myaccountname]/public_html/wp-content/advanced-cache.php on line 22 * Warning: include_once(): Failed opening ‘/home3/[myaccountname]/public_html/wp- content/plugins/wp-super-cache/wp-cache-phase1.php’ for inclusion (include_path =’.:/opt/php56/lib/php’) in /home3/[myaccountname]/public_html/wp-content/advanced- cache.php on line 22 * So, I had the WP Super Cash plugin installed in the past. I have since deleted it. Looking through FTP and cPanel, there are no wp-super-cache files left. The advanced-cache.php file is gone. The WP_CACHE define line is no longer in the wp-config.php file. I went through the steps outlined [here](https://wordpress.org/plugins/wp-super-cache/#installation). * I tried reinstalling and redeleting the plugin. * I tried switching themes as I am currently using Themify Ultra. Had the same problem on the stock WordPress themes. * I do not use a CDN. * I have cleared my browser caches. The same problem shows up on private/incognito windows in Safari, Brave, and Chrome. * The error messages do NOT display on the mobile version of the site. * Very appreciative of any ideas. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarning-include_once-wp-super-cache-error%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 13 replies - 1 through 13 (of 13 total) * [Olga Gleckler](https://wordpress.org/support/users/oglekler/) * (@oglekler) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12222299) * Hi! If advanced-cache.php failed to open wp-cache-phase1.php it must be on a server. * Plugin has this notification: “If uninstalling this plugin, make sure the directory_% s_ is writeable by the webserver so the files _advanced-cache.php_ and _cache- config.php_ can be deleted automatically.” * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12222315) * Thank you for your response. I am not sure I understand. advanced-cache.php and wp-cache-phase1.php no longer exist–they were deleted automatically when I uninstalled the plugin. I have checked for them in FTP and on the cPanel File Manager–where else could they be? * [Olga Gleckler](https://wordpress.org/support/users/oglekler/) * (@oglekler) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12222396) * I looks like you solved the problem ) I was about to suggest that you are looking in different folder like a reserve copy. * [Suman](https://wordpress.org/support/users/sumanm/) * (@sumanm) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12222402) * Hello coleenabnit, * As per my analysis,you should try this step: * 1.if possible restart or reload your apache server,It can resolve this error. * Thanks Suman W. * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224308) * [@oglekler](https://wordpress.org/support/users/oglekler/) I definitely did not solve the problem–the website is still showing the error message. * [@sumanm](https://wordpress.org/support/users/sumanm/) I have a shared hosting plan through HostGator, so I don’t think I can restart/reload the apache server, right? * [Olga Gleckler](https://wordpress.org/support/users/oglekler/) * (@oglekler) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224607) * Sometimes it’s here, sometimes it isn’t… Try to disable WP Performance Score Booster plugin. * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224620) * It is disabled. I have tried disabling all plugins and have the same issue. * [Olga Gleckler](https://wordpress.org/support/users/oglekler/) * (@oglekler) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224665) * But I see it… so, page must be cached at some point with these errors. Maybe your hosting provider offers such service? * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224688) * [@oglekler](https://wordpress.org/support/users/oglekler/) That’s what I thought too but, as I understand it, HostGator does not cache on shared plans. * [Olga Gleckler](https://wordpress.org/support/users/oglekler/) * (@oglekler) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12224852) * I’m getting out of versions… To restart your system like Sumanm suggested you can try change PHP version to another, reload your site and than switch it back again. * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12225399) * [@oglekler](https://wordpress.org/support/users/oglekler/) I have updated the PHP version but the issue is still there. Thank you for all your responses. * Thread Starter [coleenabnit](https://wordpress.org/support/users/coleenabnit/) * (@coleenabnit) * [6 years, 6 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12225756) * Hey everyone! I think the problem may be solved. Here is what I did: * – Upgraded PHP in HostGator; – Reinstalled WP Super Cache; – Set it up according to [these directions](https://www.hostgator.com/help/article/wp-super-cache-plugin);– Deleted the cache in WP Super Cache; – In cPanel File Manager, deleted the “Cache” file from the home folder; – Tested the cache in WP Super Cache (Everything looked good); – Used “Delete Cached Pages” in WP Super Cache; – Deleted the cache again. * The page now displays properly when I access it on Brave through a private window with Tor. Thank you [@oglekler](https://wordpress.org/support/users/oglekler/) and [@sumanm](https://wordpress.org/support/users/sumanm/) for taking the time to respond. - This reply was modified 6 years, 6 months ago by [coleenabnit](https://wordpress.org/support/users/coleenabnit/). * [itzsead](https://wordpress.org/support/users/itzsead/) * (@itzsead) * [6 years, 5 months ago](https://wordpress.org/support/topic/warning-include_once-wp-super-cache-error/#post-12278060) * Hello, I had the same problem on my website.
