Eloqua not tracking email clicks

Hi,

I got a question regarding email tracking, recently i sent out an email with invitation links, and as usual Eloqua added the tracking to the links.

The difference this time is that ELoqua is not tracking any clicks, and i dont understand why as every other email that i have sent out has done that.

I verified by clicking the links several times myself, but still nothing shows up.

Eloqua shows other statistics as email delivered and email opens bu no clicks at all.

the only difference is that i used Simple email campaign instead of the normal campaign builder since i had no need to continue as it was just a simple invitation email.
