Module ps_viewedproduct update from v1.1.0 to v1.2.0 using Prestashop adminconsole cause shop cart stop working PS 1.7.3.2
Update procedure says "success" but after it goods fail to be added to the shop cart. Debug mode shows no errors. Cleaning website and browser caches gives nothing. So I have to restore website from backup.
update:
if we try to disable or uninstall updated module everything back to normal.
