I'm new in typo3 and I installed typo3 version 12 on my localhost but I have problem that I can't find the templates tab under web module in my control panel of the backend
i tried to install version 11 and it works but I want to know why I can't find it in version 12
The module has been refactored and split, see Improved TypoScript and page TSconfig modules.
You can see it in your screenshot within the Site Management section.
