Hi Cathy Sirizzotti  !

Go to Woocomerce-> Status and scroll down to the bottom of the templates to see outdated files and the path to the file
then go to Appearance-> Editor-> woocomerce
Go to the file according to the path and change the version it requires (eg 3.3.0 to 3.6.0) only change the version at the top of the page without changing the content.
Your problem will be solved

thank you
