WC plugin semms switched off

We re-started to customize our 2nd InStyle website after a longer time. First we allowed all of updates (WC, Wp, etc) but after the updates the WC plugin doesn't work.
We switched OFF/ON but noting has changed.

Could you suggest us something please?

Thanks a lot,

Hi,
Could you please provide me with a URL to your website and back-end access via PM (click the “Private Message” text underneath my avatar) so that I may analyze it?

Hi,
It should be fine now - on the mainbody widget area, there's News Show Pro widgets with WC Product SKUs names (from the quickstart) as a data source, but these products are not available anymore on your website, so the error stopped other scripts. I've changed the Data Source to "Latest Woocommerce Products" and it's fine.

Dear Joshua,

Thanks a lot!
