Hi there,
we have the same problem in our shop. We have 20 active items listed in our spreadshirt backoffice at the moment. After rebuilding the WP-Spreadplugin cache we see that 20 items have been rebuilt – seems to be right. It seems like WP-Spreadplugin doesn’t delete those items that are no longer available via the API.
@jakobpanter: how did you solve this issue?
Thanks,
Alex
