Hi,

I am using a theme which has not problem with theme customizer at hidden link
But when Toolset 3.4.14 and Toolset Block Version 1.6.1 activated, theme customizer failed to function with critical error as per attached. Other than that, the website frontend and backend works fine.

Your assistance is appreciated.

Thanks
Eric

Hi Eric

That sreenshot shows that you should have details of a fatal PHP error in your logs, could you please check and share the details?

Also, is this an existing site? Did you have a View widget added on the widgets page?

If you haven't already, turn on the debug log by editing your wp-config.php file and change the line with WP_DEBUG like so:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
define('WP_DISABLE_FATAL_ERROR_HANDLER',true);

That will create a debug.log file in your /wp-content/ directory which you can examine in any text editor, but if you are only just turning on debugging now you'll need to re-create the error.

Hi,

It is showing error message as per attachment. Yes, widget has toolset view.
Looks like toolset has issue rendering on theme customizer.

That's not the error from the logs, it doesn't show what the problem is.

We have another user reporting something similar, which occured after updating to Elementor 3.5.

Does that apply to your site?

In which case you can find more details, including a patch to fix the issue here: https://toolset.com/errata/fatal-error-on-customizer-page-after-updating-to-elementor-3-5/
