The Jms Multisite 1.3.03 for joomla fixes an "Internal Server Error" that may occurs when creating a fresh Slave site on Joomla 3.0.2 and PHP 5.3.15.

The error is araise during the computation of the "refresh icon".
On prior JMS version, it is possible to avoid the error when settings the "disable the refresh icon" to yes. (See the settings menu).
