Not sure if you can help with this, but I ran a GT Metrix report on the site today and got this result:
The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 27.3KiB.
https://[redacted].com/wp-content/themes/generatepress/style.css?ver=1.4
https://[redacted].com/wp-content/themes/generatepress/style.css?ver=4.8.2
Is this an intentional redundancy on the part of GeneratePress, or do I have an extra stylesheet on my server (I see only one when I look inside /wp-content/themes/generatepress/)?
P.S. I’m getting the same message for my child theme, but also see only one stylesheet in that case as well:
