Menu crushes the website

Hi,

This should work by default but if not it means that there can be a server setting like wp memory limit to can identify what’s going on please update the theme to latest version 4.1.7 and the afferent plugins, you can check the plugin update status from wp-admin -> appearance -> install plugins.

If this is useless please follow these steps to enable wp debug:

•  Connect to your server by FTP
• Look in root directory of your WordPress install and open wp-config.php
• Search for define( ‘WP_DEBUG’, false ); and change FALSE value to TRUE

define( 'WP_DEBUG', true );

•   After this line add this:

define( 'WP_DEBUG_LOG', true );

WP_DEBUG_LOG is a companion to WP_DEBUG that causes all errors to also be saved to a debug.log log file inside the /wp-content/ directory. This is useful if you want to review all notices later or need to view notices generated off-screen (e.g. during an AJAX request or wp-cron run).

Repeat the described actions and then check the debug.log file and let me know what error appears.

if it’s something related to the php memory allocation you should follow this : http://seventhqueen.com/blog/code-snippets/increase-php-memory-limit-in-wordpress.html

Let me know

Cheers

Ok then

Have a nice week

Cheers
