Memory Exasted error and widgets.php showing blank

I am facing a problem with my wordpress dashboard . When i try to open widgets tab , widgets.php showing blanks . Some time opening well and when i try to edit widget memory exacted error comes . I increase memory in config.php using define( ‘WP_MEMORY_LIMIT’, ‘256M’ ); But still to problem persist .

Following is the code of my config.php file

<?php
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
define( ‘WP_DEBUG’, false );

/** Enable W3 Total Cache Edge Mode */

define(‘WP_CACHE’, true); //Added by WP-Cache Manager
define(‘W3TC_EDGE_MODE’, true); // Added by W3 Total Cache

How Sir where can i download newmag theme . In envato market i am not able to download it

Sir i have a account . But no download link displaying it even after login .Only buy link is displaying

If you bought the theme, then link is found in your downloads tab in your Themeforest account.
If you don’t see all the items you have purchased, you may want to contact Envato/Themeforest and explain there is a problem.

On your ‘downloads’ page under your account (if you have multiple accounts, you need to login to TF using the one you purchased either Newsmag or Newspaper with), you will see all of your purchased items and links to download the files.

Sir i upload the fresh theme again , But notice that when it activate the jetpack then the issue the widgets.php shown blank or memory exasted error comes . As i deactivate the jetpack all the issues solved . So please help me how to solve it

Jetpack causes a LOT of problems with *all* themes except those that come with WordPress, or which are based on the default themes (child themes, etc.). Generally Jetpack should never be used with any theme running visual composer unless you have dedicated server or VPS.
