[Mediawiki-l] Raw pages must be accessed through the primary script entry point

Hello I have a problem with subcluding a Template from one wiki to the other I have enabled wgEnableScaryTranscluding and set iw_local and iw_trans in the rows associated with my iw_prefix of my interwiki table. While transcluding with input {{wikiccv:annotations}} works fine subcluding with input {{subst:wikiccv:annotations}} gives this message : [Template fetch failed for http://82.226.95.82/~wiki/wikiccv/mediawiki/index.php/Template:annotations?…] which in turn gives : Forbidden Raw pages must be accessed through the primary script entry point. I am sorry, I do not understand the meaning of "primary script entry point" Could someone help ? Thanks Francois Colonna
