我用xampp Build 了一个本地TYPO3 7.2环境 . 安装工作正常，其他一切也正常 .
一开始我安装了FluidTYPO3站点kickstarter发行版，因为我想在那里使用FLUID . 分发创建了所需的所有扩展（vhs，flux，fluidpages，fluidcontent），然后我使用构建器创建了我的提供者扩展 . 它还创建了4页或1页和3个子页面 . 因为我想重命名它们，我得到以下错误/异常：
PHP Warning: file_get_contents(): Filename cannot be empty in F:\xampp\htdocs\src\typo3_src-7.2.0\typo3\sysext\fluid\Classes\View\TemplateView.php line 318
我尝试在该文件中的var_dump（）但它没有帮助 . 我在其他模块上获得了正确的路径和文件名，但没有出现错误出现的“页面”模块 . 我无法重命名，删除或编辑页面 . 似乎某些东西在那里是空的，嗯 .
后来我发现这些扩展不适用于我的TYPO3版本7.2，只考虑6.2.99 . 所以我卸载了所有扩展并从Github下载了开发扩展（https://github.com/FluidTYPO3） . 我安装了它们的错误，我的版本太高了 . 扩展仅适用于7.1.99 . 我认为这不会是一个问题，无论如何它应该适用它 .
当我测试它时，一次又一次地出现了相同的错误 .
我不知道问题出在哪里 . 在6.x安装上一切正常 . 这可能是一个错误还是我忘记了什么？
PHP Version: 5.6.3 / TYPO3 Version: 7.2
如果有人知道这个问题或者可以帮助我解决它，那将是非常好的 . 我不知道需要哪些信息 . 随意询问是否需要某些东西 .

这是函数“getTemplateSource”中的错误 .
我将php版本降级为5.5（新的xampp安装），但它没有用 . :-(
希望得到帮助，谢谢！

好吧，我认为问题已经解决了 . 问题是 table "pages" in database 的 column "tx_fluidpages_layout" 没有进入 . 它是NULL .
因为我无法更改并将其保存在页面属性中而不调用该错误，我使用phpmyadmin更改了它 .
要修复该错误，您必须手动转到数据库f.e中的 table "pages" . 用phpmyadmin然后到 column "tx_fluidpages_layout" . 你必须 edit the value and change it to "fluidpages__fluidpages" . 之后，您可以保存并重新加载后端 .
现在，您应该编辑页面属性并设置来自提供程序扩展的页面布局 .
不管怎样我认为这是一个错误，不应该发生 . 在TYPO3 6.x中，它是自动插入的 .
