Error when creating date difference fields

[enishemed]

Dear Sergey,

I am taking the following error when trying to create "Years difference" field. It occurs also for "Months difference", "Day difference" and "Hour difference" fields.

I have two systems and both have the same error.

Your hosing can't create custom mysql function that required for these field types because it's restricted.
Ask your hosting support about this issue.
