Still it does not work. * If I did this: 2- Move the wp-recaptcha.php file out of the wp-recaptcha folder so that it is in /wp-content/mu-plugins 3- Now you should have /wp-content/mu- plugins/wp-recaptcha.php and /wp-content/mu-plugins/wp-recaptcha/ * It will cause this: * Warning: require_once(/home/domain1/public_html/wp-content/mu-plugins/recaptchalib. php) [function.require-once]: failed to open stream: No such file or directory in /home/domain1/public_html/wp-content/mu-plugins/wp-recaptcha.php on line 45 * Fatal error: require_once() [function.require]: Failed opening required ‘/home/ domain1/public_html/wp-content/mu-plugins/recaptchalib.php’ (include_path=’.:/ usr/lib/php:/usr/local/lib/php’) in /home/domain1/public_html/wp-content/mu-plugins/ wp-recaptcha.php on line 45 * mu-plugins is giving me the problem, but if i download into plugins directory, it ok. * I am really curious, how did you get recaptcha working with wordpress MU??? * Thread Starter [axilaris](https://wordpress.org/support/users/axilaris/) * (@axilaris) * [15 years, 4 months ago](https://wordpress.org/support/topic/cannot-install-recaptcha-plugin-for-multisite/#post-1808118) * I found out where line 45 is in wp-recaptcha.php * if ($wpmu == 1) require_once(dirname(__FILE__) . ‘/wp-recaptcha/recaptchalib. php’); else require_once(dirname(__FILE__) . ‘/recaptchalib.php’); <–line 45 * so after printing out $wpmu, it appears to be 3. * Shouldnt it be 1 instead of 3?

There is no installation instruction for 3? or should i be using 1? if so, how to ? * Thanks.

I mean, not every plugin can work in mu-plugins. If you can network activate it, the only diff between that and mu-plugins is that a sub-site can turn OFF a network activated plugin, where as they cannot turn off a plugin in mu-plugins. * [Andrea Rennick](https://wordpress.org/support/users/andrea_r/) * (@andrea_r) * [15 years, 4 months ago](https://wordpress.org/support/topic/cannot-install-recaptcha-plugin-for-multisite/#post-1808124) * > a sub-site can turn OFF a network activated plugin, * Only if they are on the blog where it was network activated. 🙂 * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [15 years, 4 months ago](https://wordpress.org/support/topic/cannot-install-recaptcha-plugin-for-multisite/#post-1808125) * I keep forgetting to test as a non-SuperGrover… Viewing 15 replies - 1 through 15 (of 15 total) The topic ‘cannot install recaptcha plugin for multisite’ is closed to new replies. * In: [Networking WordPress](https://wordpress.org/support/forum/multisite/) * 15 replies * 4 participants * Last reply from: [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * Last activity: [15 years, 4 months ago](https://wordpress.org/support/topic/cannot-install-recaptcha-plugin-for-multisite/#post-1808125) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
