We are trying BerqWP and have been happy with the speed improvements.
However, our title fonts are not showing up properly after the pages are cached and we've been unable to figure out how to get them to show properly.
We had sent a question to BerqWP support but have not had a response yet.

Also, we use WPvivid's image optimization and even though we've selected Disabled Webp images, the images are still served by BerqWP's cache images, which causes the page to not load with images in older versions of Safari. What's the fix?

Thanks.
