Whenever I activate the plug-in as well as the rest of the plugins, the backend becomes a blank page. Only the types plugin can be used. The views, whenever it is activated, the theme customizer would not work. I am using DIVI. I got the idea of using Toolset from Divi and it is recommended by Divi, so I suppose that there should be no conflict between Divi theme and plugins with the toolset plugins. It's not working on both the Divi main theme and the child theme. Below are the screenshots of the plugins in use. I have had to uninstall some divi plugins just to accommodate the types plugin. hope you can help me solve the conflict. thanks.

Usually a white screen like this indicates a server-side problem, so the best way to determine the issue is to turn on server logs and observe the reports. If you are not familiar with server logs, I can show you how to activate them temporarily. Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Upload the new wp-config.php file to your server, then try to activate the Toolset plugins again. If the screen is blank refresh a couple of times. An error_log.txt file should be created in your site's root directory. Please send me its contents. Once that is done, you can revert the changes you made to wp-config.php. If you still see the white screen, you can log in using FTP and rename the Toolset plugin folders to deactivate the plugins and restore admin access. The folder names are "types" and "wp-views" in wp-content/plugins. You can rename them to something like "types-backup" and "wp-views-backup".

Looks like your server is running low on memory. Toolset requires a minimum of 128M by itself, and when you add Divi and WPML on top of that you probably need to increase the available memory to 256M. Sometimes you can overcome this limitation by making a change to your wp-config.php file. I would try that first. Edit your wp-config.php file and add this line just before it says "/*That's all, stop editing! Happy blogging.*/"

define('WP_MEMORY_LIMIT', '256M');

Upload the updated wp-config.php file to your server and try again. If this does not resolve the issue, you may need to ask your hosting company to help you increase the amount of memory available to WordPress and PHP. Sometimes they have global settings in place that override changes to the wp-config.php file like this.

Let me know if editing the wp-config.php file does not resolve the issue.
