Hi @enumis
does the same issue occur if you roll back to the previous version?
You can download the previous version from this link: https://downloads.www.ads-software.com/plugin/freesoul-deactivate-plugins.2.1.9.zip
You need to upload the zip from the page of plugins, not via FTP. In another case FDP will not restore the previous mu-plugin.
Rolling back will not be the final solution. I want only to be sure the last update is really the cause of the issue, or just triggered the issue.
Be sure you haven’t disabled WooCommerce in Post Types => Products or Singles => Products.
In the meanwhile I will do additional tests with WooCommerce.
Have a great day!
Jose
