通过安装工具更新TYPO3核心更新

Question

When I try to upgrade TYPO3 version from installtool, I get the following exception.

Automatic TYPO3 CMS core update not possible: Folder structure has errors or warnings
To perform an update, the folder structure of this TYPO3 CMS instance must stick to the conventions, or the update process could lead to unexpected results and may be hazardous to your system

Does anyone have an answer?

Answer 1

If you see this message you should go into the Install Tool's Folder Structure and try to solve the problems that are mentioned there. You should see a red circle with a number already next to the text "Folder structure". Like on this image:
