TYPO3 Exception 1382276561

The package "..." depends on "..." which is not present in the system.

Solution 1

Clear system caches

Solution 2

The cache cannot be cleared, because both the TYPO3 backend and the TYPO3 install tool are not available any more. Open the file typo3conf/PackageStates.php and remove the part which belongs to the extension which requires the missing extension. If everything is finally restored, then you can install this extension again manually.

Solution 3

If deleting PackageStates.php is no option, try using the typo3cms console to re-install an extension which is already installed. That should fix it.
