Module development and code questions

I'v just upgraded to 4.7 from 4.6.9 on a commercial site.

Now, i'm trying to convert images to products using the ecommerce module. To do that i need to select the edit tab in that particular node i want to convert.

Certain nodes, only a couple of them without any obvious relation between them, are showing a blank page when clicking on the edit tab. Actually, when i type in the address bar, lets say:

http://mysite.com/index.php?q=node/375/edit

, it just shows a blank page on certain nodes.

Others work fine.

What could be the reasons why they show a blank page? Has that something to do with the database?

thanks for a little assistance.

Hi,

I'm very newbie with Drupal, and I would like to have your advices.

I would like to manage a TODO list on a drupal site, similar to an event list. An event will have a deadline and/or a recurrence (repeat every week...), and I would like to receive an email with that event if it trigger the deadline or the recurrence.

Do you know a Drupal module that can do that ?

Thanks a lot.

When Attempting to send a message through the private message module I'm getting the following error.

Does anyone have a fix/idea of how to fix this?

I created a Drupal site for my boss and the URL is:

I have Event module installed and it is working correctly.

When I click on create rsvp, however, I get the following error message:

Fatal error: Call to undefined function: form_textfield() in

If anyone can tell me what is wrong and how to fix it, I would very much appreciate it!
