Title: [Plugin: WP Super Cache] Install problem 0.9.1 Last modified: August 19, 2016 --- # [Plugin: WP Super Cache] Install problem 0.9.1 * [vernonr](https://wordpress.org/support/users/vernonr/) * (@vernonr) * [17 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/) * I’m having a minor issue finishing the install of WP Super Cache…0.9.1 * When trying to access Plugins within admin backend I get a server 500 error and the line added to PHP error log states missing function admin_url on line 1395 of wp_cache.php ?? * WP Super cache tab is functional and displaying correctly.. I haven’t switched caching on as yet because of this problem… * Suggestions please… * Thanks * Status info… The basic install seems complete… Files in place. Rewrite rules added to ht.access ( I’m running Apache under Windows so .htaccess isn’t such a good name ) both in root and subdirectory as suggested. * Rest of site working properly as far as I can tell… Viewing 9 replies - 1 through 9 (of 9 total) * [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [17 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006000) * Do you get the 500 error if you comment out the following line in wp-cache.php? add_action( ‘admin_init’, ‘wp_cache_admin_notice’ ); * Thread Starter [vernonr](https://wordpress.org/support/users/vernonr/) * (@vernonr) * [17 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006053) * No I don’t get the 500 error any more – the plugins tab appears correctly. * The same happens if I comment out the line with the admin_url call… * Perhaps a new file got added..( I had originally downloaded a slightly prior version and accepted the auto prompt to upgrade when installing ) and the upgrade process fail to pick this up ? * [brentcreative](https://wordpress.org/support/users/brentcreative/) * (@brentcreative) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006178) * How do I manually deactivate this plugin? Can I do this through the database. It’s messed up my admin and I can’t get at it. I don’t want it to work at this point just remove it. Can just delete it because it then takes the whole site offline. * [Jeremy Clark](https://wordpress.org/support/users/jeremyclark13/) * (@jeremyclark13) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006179) * [http://wordpress.org/extend/plugins/wp-super-cache/faq/](http://wordpress.org/extend/plugins/wp-super-cache/faq/) Scroll down and look for the uninstall directions. * [brentcreative](https://wordpress.org/support/users/brentcreative/) * (@brentcreative) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006180) * The problem as I’ve stated is that I can’t access my admin due to conflicts with this plugin, so step one has to be done another way. * 1. Clear the cache in the backend page and then deactivate it on the plugins page. * [Jeremy Clark](https://wordpress.org/support/users/jeremyclark13/) * (@jeremyclark13) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006181) * Obviously you’ll have to skip that step. You manually delete the cache in step 5 anyway. * [brentcreative](https://wordpress.org/support/users/brentcreative/) * (@brentcreative) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006182) * Jeremy, * I’ve been trying. Any step to manually do this make the main site stop working. I’m in bit of a bad spot right now. My site Bones Over Metal.com is in serious need of Caching. However, the plugin seems to only be half working. Last night I lost the entire site and by changing my .htaccess back, I got it back. However, now I don’t have admin. * I am would like to hire someone to finish this task. Are you interested or do you know someone who is? Thanks, * Mark Brent * [brentcreative](https://wordpress.org/support/users/brentcreative/) * (@brentcreative) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006183) * I followed these steps listed above and it takes my site completely offline. What gives? * [briandavis1988](https://wordpress.org/support/users/briandavis1988/) * (@briandavis1988) * [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006194) * hello all (especially donncha) * Although I finally managed to uninstall WP Super Cache, I really do appreciate the value this plug-in has and really want to get it up and running form my blog. * Does anybody know any more about _‘500 error and the line added to PHP error log states missing function admin\_url on line 1395 of wp\_cache.php ??’_ * I have decided to try install the plug in again (God help me!), and have looked at the Troubleshooting list in the FAQ’s for help. * I need to clarify/understand the following before I start again… can anybody help: * 1. Is wp-content writable by the web server? (sorry, dont know what this means– could somebody explain?) * 8. Anything in your php error_log? (again, sorry, don’t know what this means– could somebody explain?) * 10. The plugin does not work very well when PHP’s safe mode is active. This must be disabled by your administrator. (again, sorry, don’t know what this means– could somebody explain?) * 14. Make sure cache/wpcachemutex.lock is writeable by the web server. (again, sorry, don’t know what this means – could somebody explain?) * Any other feedback, comments and ideas about ‘easy’ installation are welcome. * Brian Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘[Plugin: WP Super Cache] Install problem 0.9.1’ is closed to new replies. * 9 replies * 5 participants * Last reply from: [briandavis1988](https://wordpress.org/support/users/briandavis1988/) * Last activity: [17 years ago](https://wordpress.org/support/topic/plugin-wp-super-cache-install-problem-091/#post-1006194) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
