I installed Standalone Sitemap Generator in several of my websites in wordpress or e-commerce, has always worked perfectly, but about 10 days ago, suddenly, without touching any setting, began to fail, by the thousands of pages I had in the sitemap , I suddenly only a few hundred marks.
The strange thing is that this has happened suddenly and dalo same day in 2 different sites, one in wordpress and the other in OpenCart, so I assume that the problem does not stem from the site, as the same problem occurred in 2 sites completely different and the same day.
In addition, these sites was not at all making changes, the sitemap was generated daily in a perfect manner.
