[TYPO3-templavoila] Error when upgrade to 1.3.8

[Gideon So]

Hi list,

    I installed templavoila as a global extension because I have
serveral sites share the same typo3 soruce. Then it is easier for my to
upgrade some extensions for all sites.

    I tried to upgrade templavoila to 1.3.8 this morning but I got this
error: The extension can only be installed in the path typo3conf/ext/
(lockType=L) .

    Any clues on this??

    Thanks a lot.
