I haven’t seen that before. Are you sure all the plugin files are there? Could you try installing it again? * Kind regards, Brecht * Thread Starter [ingridprent](https://wordpress.org/support/users/ingridprent/) * (@ingridprent) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016411) * I tried to download and install the plugin again and receive the same error. * Plugin Author [Brecht](https://wordpress.org/support/users/brechtvds/) * (@brechtvds) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016412) * Have you tried installing it from the WordPress backend? So going to Plugins > Add New and searching or it? * Thread Starter [ingridprent](https://wordpress.org/support/users/ingridprent/) * (@ingridprent) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016416) * I’ve downloaded the zip-file and uploaded it: Plugins > Add new > upload. The upload works just fine. The fatal error occurs when activating the plugin. * Plugin Author [Brecht](https://wordpress.org/support/users/brechtvds/) * (@brechtvds) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016417) * I know. But can you try searching for it instead of uploading it yourself. If you go to Plugins > Add New you can search for “WP Ultimate Recipe” and install it right there, instead of downloading and uploading it yourself. * I feel like something is going wrong with the downloading and uploading which is why I’d like you to try and skip that. * Thread Starter [ingridprent](https://wordpress.org/support/users/ingridprent/) * (@ingridprent) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016444) * Tried that too.

Didn’t you find the time or is something wrong with the email address? * Could you try disabling all other plugins for a second and try activating then? Just to make sure there’s no compatibility issue. * Thread Starter [ingridprent](https://wordpress.org/support/users/ingridprent/) * (@ingridprent) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016489) * Hi, * I’m not sure I want to give you admin access to my site, Brecht. Disabling all other plugins takes me a huge amount of time! * For now, I asked someone else to help me with this issue. I’ll get back to you if needed, it that’s okay. * Thanks, Ingrid * Plugin Author [Brecht](https://wordpress.org/support/users/brechtvds/) * (@brechtvds) * [11 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016490) * You should be able to deactivate all plugins in just a few seconds, no? Just select all of them and use the select box to deactivate them all. After testing that, just activate them all again the same way. * Do you happen to have another WordPress website where you can test if you have the same problem? * [lekkermelig](https://wordpress.org/support/users/lekkermelig/) * (@lekkermelig) * [10 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-activating-plugin-6/#post-6016679) * I had exactly the same problem Then I disabled all plugins and could install this plugin After enabling all other plugins I got a whitescreen. I removed all plugins, and finally discovered the bol.com affiliate plugin was causing problems [https://wordpress.org/plugins/bolcom-partnerprogramma-wordpress-plugin/](https://wordpress.org/plugins/bolcom-partnerprogramma-wordpress-plugin/) * Disabling this plugin and I could activate, the WP Ultimate recipe plugin ENabling the affiliate plugin again and the white screen was back.
