Title: Request timeout error in backend Last modified: November 5, 2023 --- # Request timeout error in backend * Resolved [sibokker](https://wordpress.org/support/users/sibokker/) * (@sibokker) * [2 years, 7 months ago](https://wordpress.org/support/topic/request-timeout-error-in-backend/) * Hi, * I have a problem with Woocommerce where I get a request timeout error when navigating through products or the logs in the backend, for example. The frontend webshop works, but I cannot adjust products, among other things. I have tried deactivating several plugins but to no avail. Woocommerce log indicates the following:CRITICAL Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, non-static method OptimizeDatabase::odb_uninstallation_handler() cannot be called statically in /home/frent/public_html/wp-includes/class-wp - hook.php:310Stack trace: 0 /home/frent/public_html/wp-includes/class-wp-hook. php(334): WP_Hook->apply_filters() 1 /home/frent/public_html/wp-includes/plugin. php(517): WP_Hook->do_action() 2 /home/frent/public_html/wp-admin/includes/plugin. php(1269): do_action() 3 /home/frent/public_html/wp-admin/includes/plugin.php( 960): uninstall_plugin() 4 /home/frent/public_html/wp-admin/includes/ajax-actions. php(4748): delete_plugins() 5 /home/frent/public_html/wp-includes/class-wp-hook. php(310): wp_ajax_delete_plugin() 6 /home/frent/public_html/wp-includes/class- wp-hook.php(334): WP_Hook->apply_filters() 7 /home/frent/public_html/wp-includes/ plugin.php(517): WP_Hook->do_action() 8 /home/frent/public_html/wp-admin/admin- ajax.php(188): do_action() 9 {main} * thrown in /home/frent/public_html/wp-includes/class-wp-hook.php on line 310 * Is this a known problem?

It would be greatly appreciated if you could also include some screenshots to illustrate the process. * If you don’t already have a screenshot service installed, here are a few free options:  - [https://snipboard.io](https://snipboard.io/) - [http://skitch.com/](http://skitch.com/) - [http://getcloudapp.com/](http://getcloudapp.com/) * We’ll also need a copy of your site’s system status as well. You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”( after you scroll down a bit)”. Once done, please paste it here in your reply or via a text-sharing service like [https://gist.github.com/](https://gist.github.com/).:‎) * Look forward to hearing back from you. * Thread Starter

However, it’s possible that some of your plugins or themes may not be fully compatible with PHP 8.0 or higher. Detail information can be found here: [https://woo.com/document/server-requirements/](https://woo.com/document/server-requirements/) * As a workaround, you can continue using PHP 7.4 if it’s solving the issue. * However, have you tried disabling all other plugins except WoooCommerce and temporarily switching to a default theme like Storefront? After doing that, did you upgrade your PHP to 8.0 or 8.1 to see if the error reoccurs? This way, you can identify which plugin is creating this error. * Let us know how that goes. Looking forward to helping you. * Thread Starter [sibokker](https://wordpress.org/support/users/sibokker/) * (@sibokker) * [2 years, 7 months ago](https://wordpress.org/support/topic/request-timeout-error-in-backend/#post-17197554) * Hi [@shameemreza](https://wordpress.org/support/users/shameemreza/) * Thanks for the suggestions. I have changed the php version to 8.2 and deactivated all plugins except Woocommmerce + changed the theme to Twenty Twenty-Three.

Please share your findings with us here so that we can take a closer look. * Also, sometimes, browser cache or cookies might interfere with the backend functionality. Can you try accessing the backend using a different browser or clearing the cache/ cookies in your current browser to see if that resolves the issue? * Additionally, enabling `WP Debug` mode may be helpful in capturing detailed error messages when the timeout occurs. Enabling `WP Debug` mode and checking error logs might capture any specific database-related errors or warnings that could hint at resource-intensive queries. * The support guide below provides steps on enabling debug logging for the site: - [Debugging in WordPress](https://wordpress.org/documentation/article/debugging-in-wordpress/) * Let us know what you find!
