Facing the same problem – fixed it by re-enabling Google Fonts under Customizer > Typography.
Seems that it re-appeared since the last update.
Ocean Extra v2.4.2
OceanWP v4.0.2
Here’ s the info paste.
I noticed that the problem only occurred on WooCommerce pages (single products, archives) and not on regular ones.
Hope this helps narrowing down the source of the problem.
