In the case of WordPress, the default memory limit is usually 32MB. However, there are some processes that themes and plugins go through, such as importing demo content, that may require more memory than the default allocation. Therefore, it is recommended to increase the memory limit to avoid common site errors that may occur due to insufficient memory.
The easiest way is to reach out to your hosting company and ask theme to increase the PHP memory allocated to your WordPress site to 256M.
Connect to your server via FTP Find and edit the wp-config.php file in WordPress and add the following line:
define('WP_MEMORY_LIMIT', '256M');
