[Typo3] Internal Server Error on BE extension

[Guillaume JULLIEN]

Hello,

I can't use Templavoila
[typo3 3.7.0]
In the description of the extension, I get the following examples :

Errors: It seems like there is a backend module in "mod3/conf.php" which 
is not configured in ext_emconf.php

Naming errors:
tables
tt_content tt_content
pages pages
modname
0 xMOD_tx_templavoila_cm1
1 xMOD_tx_templavoila_cm2
