I am an absolute Drupal newbie, so please forgive my ignorance.
I have got an old Drupal site to manage (Drupal version 6.22).
While playing with the site I defined a new content type called My page and based on page.
After playing with it a bit I deleted it, from then on all my pages lost their content type and became uneditable.
After a lot of googling I realized that because My page was based on page, after deleting it I lost page type too. Seems a very strange logic to me, but not going to argue.
How can I restore the "page" content type? I tried to add it again, it was added OK, still all old pages remained typeless and uneditable.
The last site backup is from a couple of month ago and is irrelevant, as a lot of user content was added since.
I have an access as admin to the site's Drupal system, however I do not have a remote access to the server. Should I request it? Where should I go and what should I change?
