Errors

I have moved to 2.x-dev. Now these notices are popping up after setting things up.

I don't know if it is safe to ignore them or not.

I am able to change the date now but another problem that has popped up is that I cant make a reservation room and link it to the desired reservation category. There is no option to do so. All I see is when I try to make a reservation room, it just shows the basic page window, like I am making a basic page instead of a reservation room. See attached image. There is no way for me to link the room to the desired category.

With reference to the image, when I try to make a reservation room, I am unable to link it to any of the categories.

I made 2 categories -> Building 1 and Building 2
I made 2 rooms -> Room 1 to link to Building 1 and Room 2 to link to Building 2

But when I made both rooms, the window looked like I was making a Basic Page content type, not a reservation room.

This is with 2.x-dev.

I would also like to state that I am using SQL 2014, my website is on a Windows server. I am using Drupal 7.43.

For 1.2, when I made a reservation, the reservation was made but I was unable to access the the reservation calendar after, with the errors similar to https://www.drupal.org/node/2309107.

For 2.x-dev, as stated in my comment above, I am unable to make a reservation because the rooms are not showing up in the calendar, even though they are already made.

I would like to avoid reinstalling Drupal because I already have working modules on the site. Is there a possible fix for any of these versions? Or should I start looking for a better module to use.
