Woocommerce not showing products, Latest Enfold, Enfold child theme, WP4.9.5

Hello everyone,

I have a situation I could use some help!
Some data that might be helpful
–> WP version: 4.9.5 Enfold child theme (latest Enfold them purchased 3 days ago)

We are building a store website as a submap for example http://www.example.com/store.
Steps that were taken:
We have installed WP and purchased Enfold
Installed woocommerce among other plugins
Delete all products from woocommerce to add ours (of course all pages connected with woocommerce left intact (checkout, myaccount etc)).

We add the first variable product and it seems to work just fine.
The moment we add more products then things turn wrong.
From the second product onwards NO content is shown in the preview changes page.

Error reported once: FATAL error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 49bytes) in
blablabla.com/public_html/store/wp-contenct/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-helper.class.php on line 459.

This error was reported once and after this, the preview changes guides to just an empty website EXCEPT for the first product that is shown as it should be.

I thought this could possibly link with the default-constants.php so I changed the value there from 40 to 128

define( ‘WP_MEMORY_LIMIT’, ’64M’ );
} else {
define( ‘WP_MEMORY_LIMIT’, ‘128M’ );

I am afraid if this is the solution point, it should be increased more than 134217728 like let’s say 256.

Please feel free to share any ideas.
Thankful in advance
Have a great day.
Kind Regs
