I'm having a little trouble trying to install this on PN .726. I was wondering if it was possible or not. The trouble I am having is that I get the following error:

Code

Fatal error: Call to a member function on a non-object in /home/aaaaaa/public_html/modules/pn_todolist/pninit.php on line 39 

I tried changing permissions on that file to 777 and still the same problem. I even made the table in SQL for this but just as before nothing... Please can you help me because I would be interested in a todo list for my website. Thank you.

Hello,
pn_todolist was done just because the old pn-to-do-list module doesn't run with PostNuke .750 !! So it is no surprise you can't run it under PostNuke .726. It is coded using some features only available in .750 and making it .726 compatible would require some work but is not impossible.
As I made my best efforts to port modules so that they can run under PostNuke .750 so that people can upgrade (there is a LOT of important reasons including security ones why everyone should run .750 as soon as possible) you can understand that .726 isn't a priority for me.
My best suggestion would be to upgrade your site(s) to .750 or if for any reason this is REALLY impossible to run the old pn-to-do-list module (but I repeat this last solution isn't a good one !!)

Thanks for the quick answer. I know that PN .750 is the better version but I tried the upgrade and almost lost everything I had because it wouldn't start back up. I guess I will have to look up how to upgrade my site without loosing anything. Next weekend I will try a major backup/reinstall of the website and see if that will help out. Again thanks for the quick answer.
