Thread:Project:Support desk/Page hits are displayed with 1

After the upgrade of an wiki from MW 1.21 to 1.22 the access statistics displayed at the bottom of every page, i.e. the indidual hitcounter, is 1 ("This page was accessed once") for every page in the wiki. However, when I look at the "page" table in the database the actual number of hits is still in the "page_counter" fields. "Special:PopularPages" also displays only 1 for every page. Did somebody experience the same and is there a way to get the wiki display the correct and still stored numbers?

I did not touch any settings during the upgrade, however it was the very first time I used the webupdater (just out of curiosity).
