Appointments+ page crashing #2

Hi again,

See my previous topic :

I can not figure out how to make a reply to my own topic so i'm making a new topic.. sorry for that

@Patrick Cohen, hi Patrick thanks for your answer, here is a link to a "test" appointment page hosted on my site.

As you can see it takes years to load and then result to an "Error 500" page.

Here is a few php infos :
My memory limit is set to 1024M, max execution time to 60, post_max_size to 128M.

Thank you .
