Your issue is exactly what that errors says. You’re running out of PHP memory. I see you already have 64MB but perhaps you need 96MB or 128MB. Usually people can get away with 64 but perhaps you have a Dutch version it takes more memory but I am not sure about that.

And are you sure the breadcrumbs are generated by WooCommerce? Sometimes themes have their own breadcrumbs…

After the migration did you remember to go to permalinks and click on save twice?

Yes go to your appearance->menus and drag and drop the product categories you want displayed in your menu bar. If you don’t immediately see the product categories, move your mouse to the top right of the screen and click on “screen options” and from there you can select what is shown.

Despite my affords, if you’re still keen on doing that, you can look into the file content-product.php. That is the file that generates that h3 title tag.

You want to copy that file to your theme folder/woocommerce folder and make your edits there.

Not getting any error on my end…

Well first of all don’t use pingdom as it is the worse testing site ever. Pingdom loads everything! Do a search on Google about pingdom and you will see several indepths article on how inaccurate pingdom is.

The other thing is if having WooCommerce activated and loading some assets on pages that are not e-commerce is causing your page to slow down where you notice, then I would suggest changing host. As it should not impact your site to a point where you will know the difference with naked eye.

On the other hand if you are keen to not load any assets from WooCommerce unless on a actual e-commerce page, you can do that as well.

You can do a conditional check, probably something like this.

if ( ! is_woocommerce() ) {
wp_dequeue_script( 'woocommerce' );
}

There are other scripts you can add to that list to remove from. Checkout the woocommerce.php file in the plugin.
