CMS Made Simple Forums

Hi,

i got a strange notice on top after installing the cms on localhost :
Notice: Undefined index: extension in c:\...\include.php line 162

(But the site seems to work fine)

I searched the Line 162 of include.php = if ($path_parts['extension'] == 'php')
"Extension" is a reference to a module ?

What could be the problem ?
Thanks for your support.

Precision : this happens apparently only when i copy a local site with Dreamweaver on a distant site. Editing then a distant page could cause a problem on local (but i create a local backup of my file) ?
