我正在尝试将Typo3扩展从版本6.x升级到8.x。现在，当我尝试激活此扩展程序时出现以下错误。
TYPO3Fluid \ Fluid \ Core \ Exception抛出文件 /var/www/html/typo3_src-8.7.19/typo3/sysext/fluid/Classes/ViewHelpers/TranslateViewHelper.php在第133行。
我的locallang.xlf看起来像这样：

我的第一次尝试是比较 locallang.xlf，locallang_csh_tx_certification_domain_model_event.xlf，FormFields.html和Properties.html中的ID和键。
谢谢。
答案 0 :(得分：0)
经过长时间的调试，我们发现了问题。
问题在于命名扩展密钥和扩展文件夹。
请确保它们相同。
错了
文件夹：b_a
键：b-a
差别很小但很细致。
