You can add this to the list of benefits on your pro upgrade page, I’m sure I’m not the only one who is looking for this feature.

But the easiest probably to first lower your PHP version to 7.4 so you can access the CMS. Once back in CMS, go to Plugins-> Plugin File Editor. Make the update then change the PHP version back to 8.0. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Elementor Website Builder - more than just a page builder] Fatal Error After Updating Elementor Plugin](https://wordpress.org/support/topic/fatal-error-after-updating-elementor-plugin-2/) * [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-after-updating-elementor-plugin-2/#post-16904475) * @[salesscottbevis](https://wordpress.org/support/users/salesscottbevis/) I added the following “if” statement around line 174 and 175 of the file **/wp-content/ plugins/elementor-pro/license/api.php** and it seems to have solved the issue in PHP 8.0. I was having the same exact problem as you after upgrading. I realize it’s not ideal to edit plugin files, but when the vendor response is lagging, bandaids like that can help get the site up, at least. * ```wp-block-code if (is_array($requests_lock)): $requests_lock[ $name ] = time(); update_option( self::REQUEST_LOCK_OPTION_NAME, $requests_lock ); endif; ``` * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Frequent 404 Errors on individual events and unrelated CPTs](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 10 months ago](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/page/2/#post-16875745) * No, turning off object cache did not work, unfortunately. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Frequent 404 Errors on individual events and unrelated CPTs](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 10 months ago](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/page/2/#post-16875557) * This might work, strictly as a bandaid of course: add **flush_rewrite_rules();** at the end of functions.php * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Fatal Error in 6.0.12 / PHP8 When Visiting Appearance->Menus](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 11 months ago](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/#post-16823710) * That’s good news, thank you! - This reply was modified 2 years, 11 months ago by [Dmitriy](https://wordpress.org/support/users/dimchik/). * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Frequent 404 Errors on individual events and unrelated CPTs](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 11 months ago](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/#post-16806692) * [@joshpaynedesigns](https://wordpress.org/support/users/joshpaynedesigns/) negative.

Restoration usually involves anything that triggers permalink flush, easiest being pressing “Save Changes” on the Permalink Settings page. Disabling/enabling Events plugin also works, as does temporarily switching a theme. I’ve also noticed that it happens when someone is editing a new or existing event item, but I could not consistently recreate it as of yet. Each site with this problem had a custom permalink structure, though that in itself should not be a crime. What’s weird is that it breaks any permalinks that are not pages along with it, like other CPTs, native categories and other taxonomies. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Frequent 404 Errors on individual events and unrelated CPTs](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 11 months ago](https://wordpress.org/support/topic/frequent-404-errors-on-individual-events-and-unrelated-cpts/#post-16780245) * [@chikaibeneme](https://wordpress.org/support/users/chikaibeneme/), I appreciate the suggestion, but excluding .js and .css files from cache won’t do much in this case because these are front-end files and the page never gets to load them due to 404. It happened again today and the client now requested that I remove the plugin. * [@jcallanan](https://wordpress.org/support/users/jcallanan/), thank you for chiming in here! I am curious if you are having this issue on WP Engine or some other host. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Fatal Error in 6.0.12 / PHP8 When Visiting Appearance->Menus](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [2 years, 11 months ago](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/#post-16769547) * FYI, still an issue in 6.0.13.1 * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Fatal Error in 6.0.12 / PHP8 When Visiting Appearance->Menus](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [3 years ago](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/#post-16676843) * Thanks so much for the update and prompt support. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[The Events Calendar] Fatal Error in 6.0.12 / PHP8 When Visiting Appearance->Menus](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/) * Thread Starter [Dmitriy](https://wordpress.org/support/users/dimchik/) * (@dimchik) * [3 years ago](https://wordpress.org/support/topic/fatal-error-in-6-0-12-php8-when-visiting-appearance-menus/#post-16670727) * [@d0153](https://wordpress.org/support/users/d0153/), I am running 6.2.2 with a custom theme. I found a solution (below), but it would probably be best to test the variable before passing the value to the array_search() function in the code src/Tribe/Main.php line 3535. * In case anyone runs into this, the solution is to delete “metaboxhidden_nav-menus” keys from the _usermeta table where meta_value appears empty: * [SELECT](https://arclightcon.phpmyadmin.wpengine.net/url.php?url=https://dev.mysql.com/doc/refman/5.7/en/select.html)* FROM `XXX_usermeta` where meta_key=”metaboxhidden_nav-menus”; * Look for rows in the results where meta_value is empty and delete them.
