I installed the sitemaps plugin on 2 domains with weird results.
At first run on both sites the sitemap seems ok.
A few days later:
- on one domain all pages except the home page have disappeared from the sitemap. (initially there were 146 pages, now there is 1)
- on the other domain a few page URLs that don't exist (and never existed) have been added.
Any idea what's going on?
