Error Unable to write entry

Hello,

When i try to install Mobile joomla extension, i have this error "Unable to write entry".

If i install another extension, everything alright.

I use joomla 2.5.16

Thank you for your help

Most likely this message means that Joomla cannot unpack MJ package to temporary directory. Check permissions of Joomla's tmp directory and that there is enough free disk space to unpack MJ package into that directory (3Mb should be sufficient).
