@gorkapernas This is deployed to staging. We need just a basic check of the website (static pages, blog posts, KB, etc.).

I've run a sanity on the staging website and everything looks good, apart from a small UI issue which might not be related to the HUGO update.
Please access /pptp-vs-ipsec-ikev2-vs-openvpn-vs-wireguard/ on staging and scroll down to "Supported platforms", you will see that the content is misplaced.
Please note that this issue does not happen on production.

Updated Hugo to v0.125.3(current stable) and nodejs to v16.

Regarding the page issue, it was a bug introduced on this staging commit that is not in the production branch:

I think it is safe to revert that change on staging @jurajhilje ?

[jurajhilje]

@nathanrod Yes, you can revert that on staging.
