Hi @tendina,
I understand you’re facing compatibility issues with a third-party plugin called SG Optimizer/SiteGround Optimizer.
Please know that third-party plugins and themes are best supported by their own respective developers and we can’t guarantee their compatibility with the WooCommerce plugin.
If you’re facing an issue using a third-party plugin in combination with the WooCommerce plugin or any other plugin sold at WooCommerce.com, I’d advise giving the product developer’s guide a good look first as they are best positioned to support their products.
If you’re facing any problems with the core WooCommerce plugin, please let us know and we will be glad to assist you.
Thank you!
