How do I fix the issue of not being able to save a email template?

Make sure you have filled in all the mandatory fields before saving your template.
For example:

• The Template Name and Subject fields are required, and leaving them blank will prevent the template from being saved.
• Double-check that these fields are not empty, and ensure there are no extra spaces or invalid characters.
• Once these details are provided, you should be able to save the template without issues.
