Template name WB 2.12.1

[henri]

It is true that in WB 2.12.1 in the template name no hyphen and numbers can be used.
These characters could be applied in the previous versions.

Now I get an error message of invalid characters
[159] Template directory /template-1/info.php not exists or has invalide chars

If I change the name to templateone, I will not receive an error message

Only first Character shouldn't be a number. The regex ist [a-z_][a-z0-9_]. You change e.g. to template_one or TemplateOne
