Title: Activation Crashes Last modified: September 28, 2026 --- # Activation Crashes * Resolved [leswoolsey](https://wordpress.org/support/users/leswoolsey/) * (@leswoolsey) * [2 weeks, 4 days ago](https://wordpress.org/support/topic/activation-crashes/) * I installed version 3.1 but when I activate it it gives a fatal error.

We checked it against Category AJAX Filter 3.1. * That line is a PHP notice, not a fatal error, and it is not from this plugin. The text domain in the message is `ambition`, which belongs to the Ambition theme. This plugin’s text domain is `category-ajax-filter`. WordPress added this notice in version 6.7 when a theme loads translations too early. The same message is already reported on the Ambition theme support forum: [https://wordpress.org/support/topic/function-loaded-too-early/](https://wordpress.org/support/topic/function-loaded-too-early/) * It is written to debug.log on normal page loads while debugging is turned on, including the moment you click Activate, so it can look connected even though it does not stop this plugin from running. * Please check Plugins → Installed Plugins and see whether Category AJAX Filter shows as Active. If the site is showing WordPress’s “There has been a critical error on this website” message, look in debug.log for a separate line that starts with `PHP Fatal error` at the same time, and paste that line here. The notice you already sent is not that error. Looking forward.Thanks * Thread Starter [leswoolsey](https://wordpress.org/support/users/leswoolsey/) * (@leswoolsey) * [2 weeks, 3 days ago](https://wordpress.org/support/topic/activation-crashes/#post-19031224) * The plugin is not activated. Every time I try it says there is a fatal error. Here is a snippent from debug.log when I tried to activate it. * 28-Sep-2026 12:21:00 UTC] PHP Notice: Function _load_textdomain_just_in_time was called **incorrectly**.

That fatal error is a naming conflict: both Category AJAX Filter and Quick Event Manager declare a function named `duplicate_post()`, so PHP stops when the two plugins are active together. Deactivating Quick Event Manager lets ours activate, which matches what you found. * We are fixing this so both plugins can run at the same time, and we will release the update today. After you update Category AJAX Filter, you can activate Quick Event Manager again and use them together. * Thanks again for the clear report.
