Title: PHP 5.2 Fatal Error in cache.php Last modified: August 18, 2016 --- # PHP 5.2 Fatal Error in cache.php * [pulponair](https://wordpress.org/support/users/pulponair/) * (@pulponair) * [19 years, 7 months ago](https://wordpress.org/support/topic/php-52-fatal-error-in-cachephp/) * Hi there, after upgrading to PHP 5.2 i recieve “PHP Fatal error: Call to a member function get() on a non-object in /var/www/xxx/htdocs/wp-includes/cache.php on line 29” This seems to be related to some changes made in php5.2 regarding object handling. See [http://www.php.net/UPDATE_5_2.txt](http://www.php.net/UPDATE_5_2.txt) and [http://www.php.net/ChangeLog-5.php#5.2.0](http://www.php.net/ChangeLog-5.php#5.2.0) * Any ideas how to workaround this? Disabling the cache does not work at all.

I guessed “additional”( given that there was nothing in lines 28 or 187). I re-uploaded the cache.php file, and then the blog would not load at all. * I’m also tracking this problem over here: * [http://wordpress.org/support/topic/96746](http://wordpress.org/support/topic/96746) * [inspired2write](https://wordpress.org/support/users/inspired2write/) * (@inspired2write) * [19 years, 6 months ago](https://wordpress.org/support/topic/php-52-fatal-error-in-cachephp/#post-476754) * Good thread to start. I’ve pondered the idea of upgrading my site to php 5.2 but was concerned if it would goof something up. * I wonder if it would make any difference to disable the cache setting in the WordPress dashboard before doing the upgrade? I don’t know much about php upgrading, but it was just a thought that came to mind. * [blork](https://wordpress.org/support/users/blork/) * (@blork) * [19 years, 6 months ago](https://wordpress.org/support/topic/php-52-fatal-error-in-cachephp/#post-476755) * Where do you disable the cache? I looked all over and didn’t see anything like that. * And if I disable the cache, will that just break something else? (I assume the cache is there for a reason…) * [blork](https://wordpress.org/support/users/blork/) * (@blork) * [19 years, 6 months ago](https://wordpress.org/support/topic/php-52-fatal-error-in-cachephp/#post-476756) * Whoa! The problem has been SOLVED! * It was nothing I did — apparently there IS A PROBLEM WITH WORDPRESS and PHP 5.2! This problem appeared when they upgraded me to PHP 5.2 earlier in the week (I only made the connection a few minutes ago). So my host downgraded me to PHP 4 and now the blog works just fine. * [inspired2write](https://wordpress.org/support/users/inspired2write/) * (@inspired2write) * [19 years, 6 months ago](https://wordpress.org/support/topic/php-52-fatal-error-in-cachephp/#post-476757) * Hi blork, Glad to hear your problem is resolved. In regards to disabling the cache if you need to, it is here: * Dashboard > Options > WP-Cache * Then you can select to either disable or enable the cache. Sometimes when I’ve done changes to my template the only way I could get the change to show up right away was to disable the cache and then later go back in and re-activate it. No harm done by doing so, at least from my understanding. I don’t know if maybe the newest version of WordPress eliminated that challenge or not. I haven’t tested it since upgrading. * I don’t know if that would have helped or not in regards to upgrading to PHP 5.2 but I think I will hold off on upgrading mine for now until more people report having success with it.
