Error 500 while using visual composer and customizer

Have been trying to resolve this issue all day and the site is 90% ready to launch! When I click to edit a text box on visual composer it hangs. Chrome’s developer console reports a 500 error. I also cannot access customizer. My host advises me that I need to reinstall the theme and all the plugins with updated versions but everything is up to date so I am not sure that will help. I also have quite a bit of css in the customizer’s custom css area so I am afraid that I will lose that and have to rewrite the whole site.

Also, have been trying to find a decent popup plugin and have come up with conflicts for each one I have tried. I need recommendations.

Hi There,

Could you please try adding the following code into your wp-config.php file in the root of your WordPress installation.

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

If that doesn’t help, would you mind providing us with login credentials(by clicking on the Secure Note button at the bottom) so we can take a closer look? To do this, you can make a post with the following info:

  • Link login to your site
  • WordPress Admin username / password
  • FTP credentials

Thanks.
