Hello,
I upgraded my Prestashop from 1.4.0.17 to 1.5.6.0 with 1-click upgrade. All went fine, the site is running well, except for the sitemap generation.
Google sitemap version is 2.3.1, and after generation, a file is generated:
www.sitename.it/1_it_0_sitemap.xml, instead the file www.sitename.it/sitemap is empty.
When I submit the new sitemap to the webmaster tool, I receive an error from WMT: "the format data is wrong", and in additional before prestashop upgrading, the sitemap included around 1700 files, with the new version include around 1200 files.
Could you help me on this important matter?
Thanks Vincenzo
