Title: Internal 500 error when activating Last modified: August 21, 2016 --- # Internal 500 error when activating * [Hobstweedl](https://wordpress.org/support/users/hobstweedl/) * (@hobstweedl) * [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/) * Hi there, I’m running a multisite installation and am having problems activating the plugin. * I manually install the wp-biographia plugin, and go to the plugins page to enable it, but afterwards receive a 500 internal error, whether its on the admin pages or any of the public pages. This happens for both network activating as well as activating on a site by site basis. * I checked the apache logs and ran into these errors * ``` [Wed Sep 18 06:54:54 2013] [error] [client XXX.XX.XX.XXX] WordPress database error Table 'wp_signups' already exists for query CREATE TABLE wp_signups (\n domain varchar(200) NOT NULL default '',\n path varchar(100) NOT NULL default '',\n title longtext NOT NULL,\n user_login varchar(60) NOT NULL default '',\n user_email varchar(100) NOT NULL default '',\n registered datetime NOT NULL default '0000-00-00 00:00:00',\n activated datetime NOT NULL default '0000-00-00 00:00:00',\n active tinyint(1) NOT NULL default '0',\n activation_key varchar(50) NOT NULL default '',\n meta longtext,\n KEY activation_key (activation_key),\n KEY domain (domain)\n) DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci made by wp_upgrade, make_db_current_silent, dbDelta ``` * There are actually a number of database errors regarding different tables such as wp_registration_log, wp_sitemeta, wp_blogs. Anybody have an idea of how to correct the issue? * [http://wordpress.org/plugins/wp-biographia/](http://wordpress.org/plugins/wp-biographia/) Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Author [vicchi](https://wordpress.org/support/users/vicchi/) * (@vicchi) * [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/#post-4140487) * Hi … * Although WP Biographia hasn’t been formally tested with network/multisite installs, I’ve not had any reports of problems. * A quick search for errors such as those you’ve mentioned, seems to indicate that these can be caused by upgrading between WordPress versions for network/multisite installs. Have you recently done this? * Also, is there any reason why you’ve done a manual install of the plugin and not one via the WordPress dashboard? * Have you also tried the usual troubleshooting mechanism of disabling all other plugins before enabling this one? There might be some unforeseen clash between WP Biographia and any other plugins you have installed and active. * -Gary * Plugin Author [vicchi](https://wordpress.org/support/users/vicchi/) * (@vicchi) * [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/#post-4140500) * One other point … it looks like there’s a Trac ticket open for these errors when upgrading multisite/network. See [https://core.trac.wordpress.org/ticket/22134](https://core.trac.wordpress.org/ticket/22134). This isn’t currently fixed, as the milestone (previously for v3.6) is now ‘Future Release’. * I’m still not convinced that this is a plugin issue, but I’d be interested to hear your answers to my earlier questions on this. * -Gary * Thread Starter [Hobstweedl](https://wordpress.org/support/users/hobstweedl/) * (@hobstweedl) * [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/#post-4140676) * All of the blogs on the multi-site are updated to the latest version (3.6.1) and all plugins and themes are up to date. * The manual installations are done to in order to limit the number of plugins that are available. There are several dozen blogs being hosted with hundreds of users with editing and administrating roles. Automatic plugin and theme installations are disabled and everyone must go through me to get plugins and themes approved for use. If a plugin causes a problem (such as wp-biographia), it is easier for me to find the issue and fix it. * Unfortunately, due to the size of the multi-site setup, I cannot disable and check against all plugins. However, I can check the plugins currently active for any conflicts and get back to you. * Plugin Author [vicchi](https://wordpress.org/support/users/vicchi/) * (@vicchi) * [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/#post-4140700) * Thanks; that would be helpful. I’ve got a spare domain so I’ll set up a multisite install and test on that. Are you using (sub)domains or paths for your install? * I still think that the database errors you’ve seen are unrelated to this. They look like the result of either creating or upgrading database tables and WP Biographia does neither of these (I’ve just checked the plugin’s code base to be 100% sure of this). * What I want to track down is whether the 500 error is a result of the plugin being activated in a multisite environment, whether this is a clash with another plugin (which is possible, given there’s so many plugin combinations possible) or whether this is just pure coincidence. * -Gary Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Internal 500 error when activating’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/wp-biographia_f0f0f0.svg) * [WP Biographia](https://wordpress.org/plugins/wp-biographia/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-biographia/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-biographia/) * [Active Topics](https://wordpress.org/support/plugin/wp-biographia/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-biographia/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-biographia/reviews/) * 4 replies * 2 participants * Last reply from: [vicchi](https://wordpress.org/support/users/vicchi/) * Last activity: [12 years, 8 months ago](https://wordpress.org/support/topic/internal-500-error-when-activating/#post-4140700) * Status: not resolved
