Hi,

I got the below error first when after changing a template I ran runJobs.php to update all affectted pages. Since I was not completely sure that I updated to the new store correctly, I repeated the upgrade steps on [1] and got until the first call to SMW_refreshData when I got the error again. Did I miss some setting? Is there a workaround?

(143) Processing ID 208 ...
The property id to add must be a positive integer
