Hi,
we recently upgraded one of our sites www.kinderwagen.com from version 1.3. to version 1.5. We tested for a long time and cannot find any issue.
Our site ranked very well on google before. Now three weeks after the upgrade, we lost 20-30 % of our SEO traffic.
Does anyone have experience with such upgrades or can help us analyze the problem.
Thanks for your help.
Dieter
