Hi gzelasco,
Thanks for reaching to us.
– You should deactivate all plugins (except Required Plugins) and then reactivate them one by one. This makes it very easy to isolate the plugin causing problems.
– I see you are using outdated WoodMart theme and WoodMart Core plugin, please create a dev site and update theme and core plugins to the latest version and let me know if it helps.
Devsite – also called a Staging platform where you can test issues, enable/disable features/plugins thus such changes will affect the main site. The below article will help you to create it:
