I need an advice please. On both in admin and vendor account cannot create shipping option. When click "Create" getting error 500 on page. Same with already created shipping options. If updating and click "Save" same error 500 but the data/changes is saved. This is happened after upgrade to latest MV 4.11.01.
Have you checked logs? 500 is usually a mod_security error
Thank you for pointing to the right direction. Found out issue. Simtech addon Google translator not working correct when trying to save or create shipping.
