Fixed by adding quip and getPage extras. The artilces docs do not say which other extras are required.
i am using Articles 1.7.6
There should be a 'show_in_tree' field in the site_content table. Have you checked that for the articles?
all my articles show_in_tree field is 0 and my articles containers (parents) field is 1.
This is normal with the current version of Articles (and I should have mentioned this earlier). To see them in the Manager, you right-click on the Articles container and select "Manage Articles". If you want them to show in the tree, you can change the show_in_tree field to 1 (and I think there's a setting in Articles to make that the default).
The problem is that i cannot see the articles when i click manage articles!!!
And in the case that i create a new one, the article shows at the front only!!!
I found that an article titled how to make a blog in MODx or something like that. This article mentions several extras that the Article instructions did not mention. When I installed these extras
the Article extra began to work. Sorry I should have kept better notes. I may be wrong but I think that was the answer. Its fixed for me now.
