Most of the Issues that we get in our support mail are not actually the Plugin issues. Most of it are general WordPress issues which have nothing to do with the plugin and which can be fixed on your own.
So below are some of the lists which might be the possible cause of the issue you are facing:
1. WordPress Version: You might be using a WordPress version below 4.9. It should be minimum 4.9 or greater.
2. PHP Version: This has been the case for most users. You might be using a PHP version lesser than 5.6. It should be a minimum of 5.6 or greater. But V7.0 is always recommended.
3. MySQL Version: MySQL version should be 5.0 or greater than 5.0
4. Conflict with other Plugins: If none of the above solves your issue, possibility that it might be due to a conflict with any of your Plugin which might be outdated. Try deactivating all your Plugins one-by-one and find the culprit. If that plugin is outdated or no longer needed, delete that plugin or find a better alternative.
5. Increase PHP Memory Limit in WordPress: This is again one of the common errors with the WordPress websites. To increase the PHP Memory limit in WordPress:
First, you need to edit the wp-config.php file on your WordPress site. It is located in your WordPress site’s root folder, and you will need to use an FTP client or file manager in your web hosting control panel.
Next, you need to paste this code in the wp-config.php file just before the line that says ‘That’s all, stop editing! Happy blogging.’:
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
This code tells WordPress to increase the PHP memory limit to 256MB.
Once you are done, you need to save your changes and upload your wp-config.php file back to your server.
