Hi There,
Thanks for writing in! First of all, could you please try checking your server configurations.
You can install this plugin (https://wordpress.org/plugins/wp-serverinfo/) then head over to Dashboard -> WP-Serverinfo to check your server information.
-Check your PHP version running on your server and make sure that you’re using PHP 5.6.32 or later version.
-PHP Max execution time we recommend at least 120 seconds or higher
- Check your WordPress permalink settings. Head over to Settings -> Permalinks section and choose the option
Postname
and save changes to regenerate your permalink settings.
Also try adding the following code into your wp-config.php file which is at the root of your WordPress installation.
define( 'WP_MEMORY_LIMIT', '512M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
You can add it before the following line:
/* That's all, stop editing! Happy blogging. */
If you’re using any caching plugins, make sure to disable it temporarily and if you’re using ClodFlare, please refer to the following article (https://xthemetips.com/using-cloudflare-rocket-loader-with-x-pro-and-x5/928/)
Let us know how it goes.
Thanks!
