Hi.
1. Do you seek support for Evolve 4.2.5? This is the free theme, it is not supported in this forum, the support is by WordPress community on WordPress.org. If you purchased the paid version (and I assume that you did, since you are here), then switch to it and let me know if the problem persists. Evolve+ current version is 4.9.2.2 Wocommerce templates are being updated from time to time, and we release new once when we theme is updated. Another one is coming soon and if the templates need to be renewed they will be.
2. This, of course, can’t be – our theme practically since the start is responsive (9 years or so 🙂 ). This is either a mistake in Google Search Console (it does happen), or something else is causing this. I suggest the following: add [email protected] to the your Google Search Console, we will take a look at the error.
