[W3C Process] Specberus errors when attempting to publish SHACL spec

I was trying to publish a new version of the SHACL spec using Echidna 
but this time got two new errors that I cannot explain:

"specberus": {
         "status": "failure",
         "errors": [
           {
             "key": "no-disclosures",
             "type": {
               "name": "sotd.pp"
             }
           },
           {
             "key": "no-homepage",
             "extra": {
               "homepage": "http://www.w3.org/2014/data-shapes/"
             },
             "type": {
               "name": "sotd.group-homepage",
               "section": "document-status",
               "rule": "WGLink"
             }
           }
         ]
       },

To me these look like problems in the header metdata, but I am not aware 
of changes from our side. I tried to make sense of this using 
https://www.w3.org/pubrules and the little info that I could find on 
specberus, but maybe those more experienced with the W3C process (cough, 
Eric) may have seen this before?

(Besides, what would be the URL to give to the pubrules test server? I 
tried 
https://raw.githubusercontent.com/w3c/data-shapes/gh-pages/shacl/index.html 
but that produces 28 errors).

Thanks!
