Hi,

I just tried to install SIG (plugin_jw_sig-v1.2.1r2_j1.5.zip) on Joomla 1.5.9 and I'm getting the following error messages:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in ..../httpdocs/libraries/joomla/installer/helper.php on line 142
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in ..../httpdocs/libraries/joomla/installer/helper.php on line 142
Warning: Invalid argument supplied for foreach() in ..../httpdocs/libraries/joomla/installer/helper.php on line 187

along with error messages stating that JFolder::files/folder paths are not leading to an available directory and that there is not XML Setupfile included in the package...

Any ideas how to fix this?

(other installed plugins: Linkr and Joomfish)
