I'm having an issue where I cannot complete CS-Cart and add-on upgrades. I receive an error that says: ErrorMessage could not be sent.
Mailer Error: Could not instantiate mail function.
I previously set up SMTP with Amazon SES, but kept receiving the same errors when trying to save the settings. I then set up php mailer and chose that option in the Email settings in the CS-Cart admin dashboard, but I'm still receiving mail errors. In addition to that, the previous SMTP settings from SES are still populating the Email settings SMTP form, even though I delete them and save.
