Hi there,
It’s not required, it just helps reduce the number of resources your site loads. We’re using it here on this website.
The error you’re trying to fix is the fact that your site is loading 76 resources. The theme itself only loads 3-4 depending on your settings – the rest are coming from other plugins you’re using. It’s also saying redirection error, which could be caused by the CDN you’re using.
If you want to reduce the number of requests, you need to use a caching/minifying plugin, which will combine all of those files into 1 or 2 requests. Either that or you need to choose plugins that load fewer resources.
Autoptimize is just one plugin that does that. There are countless other caching/minifying plugins out there that serve exactly this purpose.
Of course, feel free to shoot us an Account Issue email if you’d like a refund: https://generatepress.com/contact
