Title: Call to undefined function opcache_reset Last modified: February 14, 2020 --- # Call to undefined function opcache_reset * Resolved [Tyrosh](https://wordpress.org/support/users/iskmogul/) * (@iskmogul) * [6 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-opcache_reset/) * So I just installed Google Site Kit to handle Analytics/GTM after another plugin that was doing the job was ruined by an update. No problems getting it set up aside from a small hiccup with GTM that was easily resolved. * The real issue become apparent when I went to update other plugins. Anytime I install a new plugin, or update an existing one, I get an “Update Failed!” message and am redirected to the plugin update page that displays an error referencing this plugin. * PHP version: Litespeed 7.3.14 * LiteSpeed Cache plugin is also installed, but Google Site Kit’s files should be exempted from caching. I already tried resetting Google Site Kit, no change. Also exempted the plugin files in Cloudflare, no apparent change there either. * Here’s the text of the error in question as it appears on the plugin update page.( with identifying domain info removed for security) * Fatal error: Uncaught Error: Call to undefined function opcache_reset() in /wp- content/plugins/google-site-kit/google-site-kit.php:102 Stack trace: #0 /wp-includes/ class-wp-hook.php(290): googlesitekit_opcache_reset(Object(Plugin_Upgrader)) # 1 /wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array) #2/ wp-includes/plugin.php(478): WP_Hook->do_action(Array) #3 /wp-admin/includes/ class-wp-upgrader.php(836): do_action(‘upgrader_proces…’, Object(Plugin_Upgrader), Array) #4 /wp-admin/includes/class-plugin-upgrader.php(108): WP_Upgrader->run( Array) #5 /wp-admin/update.php(138): Plugin_Upgrader->install(‘[https://downloa…’](https://downloa…’);)# 6 {main} thrown in /wp-content/plugins/google-site-kit/google-site-kit.php on line 102 Viewing 6 replies - 1 through 6 (of 6 total) * Thread Starter [Tyrosh](https://wordpress.org/support/users/iskmogul/) * (@iskmogul) * [6 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-opcache_reset/#post-12434984) * I’m dumb, found the solution minutes after making this. I hadn’t enabled OPCache in my PHP config. * [Renee Johnson](https://wordpress.org/support/users/reneesoffice/) * (@reneesoffice) * [6 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-opcache_reset/#post-12437560) * [@iskmogul](https://wordpress.org/support/users/iskmogul/) thanks for your report and follow up! Which version of the plugin were you on previously? * [gabstero](https://wordpress.org/support/users/gabstero/) * (@gabstero) * [6 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-opcache_reset/#post-12437615) * The sad thing is that my hosting company wouldn’t let me enable opcache as i am in a “share hosting”. * Any other ideas what to do? Thanks! * [gigi13](https://wordpress.org/support/users/gigi13/) * (@gigi13) * [6 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-opcache_reset/#post-12437620) * I had a similar error to iskmogul when updating from version 1.2.0 to 1.3.0 today.
