Memory limit exceeded

Hello,

Thank you for this great plugin.

I have memory problems with pwb-all-brands shortcode. I tried to deactivate all plugins except woocommerce and PWB (child theme deactivated too). The error takes longer to appear but finally it does.

I have using last versions of components: WP 5.5.3 · WOO 4.7 · Storefront 2.9.0 · (all plugins updated)

I created brands listing page with only shortcode:
[pwb-all-brands per_page="20" image_size="thumbnail" hide_empty="true" order_by="name" order="ASC" title_position="before"]

I have +100 brands and +4000 products with variations. Navigating for different pages of brands listing is slow and finally the error appears:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in /var/www/vhosts/ ... /wp-includes/meta.php on line 1064

I know that could ask to hosting guys to raise php memory_limit but the problem will be still there.

Could you help me?

Tell me if you need credentials to access.

Regards.
