Product Page with Spectra on Siteground not displaying CSS correctly

[ad_1]

I deleted all the caching, yet siteground + spectra is not working. I cleared cloudflare caching, siteground caching, disabled siteground optimized, disabled js & css minifying, removed jetpack plugin, removed siteground plugin (after disabling and purging caches), regenerated assets with Spectra, yet it shows it well in the editor, but not after publishing.

For example on this:

This is how it should look like for container with bkg + FAQ:
