 * This problem exists on at least two of my websites (both under the same domain).
   When I select ‘Customize’ I get a memory overflow fatal error—

   Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate

 * Hello,
 * The error notice that you are referring to is usually caused by the exceeding
   of the WordPress memory limit. By default, WordPress automatically tries to increase
   PHP memory limit if it is less than 64MB. However, 64MB is often not high enough.
 * To fix the issue, you can try **increasing the memory limit** by pasting in the
   following code in your **wp-config.php** file.
 * `define( 'WP_MEMORY_LIMIT', '256M' );`
 * This will increase the memory limit size in your site that should allow you to
   load the customizer without errors.
 * For more details on the issue you can also use the reference below :

 * For future reference, you can also post your issues / queries in the theme’s 
   official support forum for dedicated and swift support at : [https://catchthemes.com/support-forum/forum/clean-box-free/](https://catchthemes.com/support-forum/forum/clean-box-free/)
 * Hope this Helps,
 * Best Regards !!
