I have created a new template site and I wanted to add a new subsite to my network using this new template, but I get the following error message:
Insertion Error: Column 'post_mime_type' cannot be null - The template was not applied. (New Blog Templates - While copying posts)
New subsite has been created, but no content or options cloned from the template.
This is happening only with this new template, other templates are working.
