Hello list, nobody replied to my last post: forum: "warning: in_array(): Wrong datatype for second argument..." :-) I have made a fresh install and started from scratch, verifying that every single step would not cause any errors. Finally, I discovered and isolated the issue. When you configure a content type, for example: /admin/node/configure/types/forum you *must* al least select one checkbox among the default options: Published In moderation queue Promoted to front page Sticky at top of lists Create new revision If you leave them all unchecked (that was my case), you get the following errors when you try to add content of that type: warning: in_array(): Wrong datatype for second argument in [path-to-site]/modules/node.module on line 1296. warning: in_array(): Wrong datatype for second argument in [path-to-site]/modules/node.module on line 1297. warning: in_array(): Wrong datatype for second argument in [path-to-site]/modules/node.module on line 1298. warning: in_array(): Wrong datatype for second argument in [path-to-site]/modules/node.module on line 1299. warning: in_array(): Wrong datatype for second argument in [path-to-site]/modules/node.module on line 1300. I think you can easily duplicate the issue… Is it a bug or something I am missing? Thank you in advance for your patience! :-) -- Gabriele Caniglia
