After I installed the RSS extension, I set up some RSS feeds which only displayed an SSL certificate error ("SSL certificate problem: unable to get local issuer certificate"). To fix this, I had to check my php.ini file. Specifically, the following 3 settings: curl.cainfo, openssl.cafile, and openssl.capath. Mine were commented out. Make sure they are set to a current .pem file (I used the Mozilla CA certificate store in PEM format from https://curl.se/docs/caextract.html).
The process is described well here. This resolved my error. Hope it helps anyone else who finds this.
