Title: [Plugin: Posts 2 Posts] Fatal Error on activation Last modified: August 20, 2016 --- # [Plugin: Posts 2 Posts] Fatal Error on activation * Resolved [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/) * Hi Scribu, For some reason, after deactivating your plugin to see why WP-Migrate- DB was not working I cannot seem to be able to reactivate it. When I try to activate it I always get: Plugin could not be activated because it triggered a fatal error. * Looking throught the log I can see this line referring to PHP: PHP Fatal error: Call to undefined function scb_register_table() in D:\\…\\plugins\\posts-to-posts\\ core\\storage.php on line 11 * Thanks, * Mauro * [http://wordpress.org/extend/plugins/posts-to-posts/](http://wordpress.org/extend/plugins/posts-to-posts/) Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/page/2/?output_format=md) [→](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/page/2/?output_format=md) * Plugin Author [scribu](https://wordpress.org/support/users/scribu/) * (@scribu) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523301) * What version of Posts 2 Posts are you using? * Do you have any other plugins of mine activated? * Thread Starter [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523303) * Hi Scribu, Upon further investigation looking at the error logs, when the plugin was activated and working, it seems that it was not “seeing” my custom post types. I was getting the following errors: PHP Notice: Post type ‘ups’ is not defined. in …\\wp-content\\plugins\\posts-to-posts\\core\\type-factory.php on line 35, referer: [http://localhost/my_site/products/ups/](http://localhost/my_site/products/ups/) * Hope this helps. * thanks * mauro * Thread Starter [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523306) * I’ve tried both 1.1.3 and 1.1.4. This is the only plugin that I have from you. * thanks * Plugin Author [scribu](https://wordpress.org/support/users/scribu/) * (@scribu) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523310) * With P2P 1.1.4, open `posts-to-posts/scb/load.php`. What does it say on the first line? * Also, you don’t have the scb framework loaded in mu-plugins, by any chance, do you? * Thread Starter [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523353) * Hi, No scb framework on mu-plugins (I don’t have this folder). The first line on the load.php file reads as follows: * ``` $GLOBALS['_scb_data'] = array( 47, __FILE__, array( 'scbUtil', 'scbOptions', 'scbForms', 'scbTable', 'scbWidget', 'scbAdminPage', 'scbBoxesPage', 'scbCron', 'scbHooks', ) ); ``` * thanks * mauro * Thread Starter [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523364) * I can’t seem to find previous versions of the plugin in github. Do you have a repository of previous versions to see if it works with previous versions? * thanks, * mauro * Plugin Author [scribu](https://wordpress.org/support/users/scribu/) * (@scribu) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523368) * Go here: [http://wordpress.org/extend/plugins/posts-to-posts/](http://wordpress.org/extend/plugins/posts-to-posts/) * and find the “Other Versions” link. * Thread Starter [argeee](https://wordpress.org/support/users/argeee/) * (@argeee) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523378) * Hi Scribu, with 1.0.1 works. No error on the Apache log nor activating. Tried 1.1.3 and still get the fatal error activation error. This is the error while activating 1.1.3: PHP Fatal error: Call to undefined function scb_register_table()…\\ Uniserver3\\www\\eq_power\\wp-content\\plugins\\posts-to-posts\\core\\storage. php on line 11, referer: [http://localhost/eq_power/wp-admin/plugins.php?plugin_status=recently_activated](http://localhost/eq_power/wp-admin/plugins.php?plugin_status=recently_activated) * Rgds, * Mauro * In the mean time I will keep working with 1.0.1.

I’ve deactivated all the plugins and reactivated posts-to-post. Got, scbFramework candidates: \eq_power\wp-content\plugins\posts-to-posts\scb – r47 Asked to to upgrade connections but updated none. * I have updated the scb version for wp-pagenavi (didn’t realize it was yours) and activated all the other plugins and now works. * Thanks again, * mauro * [Marko Heijnen](https://wordpress.org/support/users/markoheijnen/) * (@markoheijnen) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-posts-2-posts-fatal-error-on-activation/#post-2523523) * Do you also have WP-PageNavi installed? That plugin will cause an fatal error when active. * Disable it. Enable post 2 post and then enable WP-PageNavi works fine.
