[TYPO3-templavoila] Templavoila 1.9.0 with TYPO3 6.1.5 problem with tabmenu

[Harald Amelung]

Hello,

I've just updated Templavoila to Version 1.9.0 on an installation of 
TYPO3 Version 6.1.5

After the update the backend shows errors.

PHP Warning: filemtime(): stat failed for 
/typo3/sysext/backend/Resources/Public/JavaScript/tabmenu.js in 
/typo3/sysext/core/Classes/Resource/ResourceCompressor.php line 307

PHP Warning: filesize(): stat failed for 
/typo3/sysext/backend/Resources/Public/JavaScript/tabmenu.js in 
/typo3/sysext/core/Classes/Resource/ResourceCompressor.php line 307


It seems as if there is not such a file 
/typo3/sysext/backend/Resources/Public/JavaScript/tabmenu.js

Is version 1.9.0 incompatible with TYPO3 6.1?

Best
Harald
