Upgrading Drupal

I've recently upgraded my drupal site from 4.7.1 to 4.7.7, and in doing so I seem to have lost the ability to create an event type. What I mean by this is that when I go to the create content tab, I have the ability to create a book page, forum topic, group, page, poll, or story, but not just an 'event'. The event module is enabled, and I do get the calendar in my menu. I can click on events that I've made prior to the upgrade and they show up fine.

I am not able to display the profile field information in version 5.2 (as i am used to with 5.1 version) using the following code.please help me out

Sup,

I am moving a Drupal 4.7 instance from a hosting provider to an in-house server.

The structure is a single codebase with multiple blog instances, about 60 in all.

I have done the following:

Hi

Is there any word editor tool in drupal 6.0, similar to TinyMCE? If there is one then do you know how to make it work?

Thanks

Hi, there:

I try to update some modules yesterday while I got email notification.
As usually, when I upload one bad code module, it's caused the module list page malfunction: "white and nothing there" page.

So I delete the bad module. But when I finally saw the module list page again, the page content only include the core modules. The names of modules which I installed all disappear! The strange thing is all modules functioning well, like penal or simplemenu, but I can't find them at admin pages.
