Error when install with Joomla 1.5.17

Fatal error: Call to undefined function JText() in /administrator/components/com_mobilejoomla/uninstall.mobilejoomla.php on line 511

I got the fatal error above, when i had installing this extensions into Joomla 1.5.17.

Please help me.

tks

Thanks for bug report, there is actually unfortunate misprint with call of JText() instead of JText::_().

The fact that error arises on line 511 means there is problem with installing "Mobile Joomla Bot" plugin (the reason is not clear, most likely it's because of access restriction for /plugins/system directory).

After i set permission for this folder, everything is done.
Thanks
