The aypsite.org site, including the public forum, has been down for several days, and now it is back.
The SSL (HTTPS) security on the site expired, and while it was renewed well in advance, it was not able to be installed on the server. This was finally fixed by installing the entire site on another server, a lot of work for our tech consultant.
Fortunately, aypsite.com and AYP Plus were not affected.
