This may or may not be an incorrect error. This error is most likely referring to the contacts between the camera body and the lens. Since you are using an off-brand lens, it is possible that there is a compatibility problem with the communication between the camera and lens. Has that body worked before with that lens under those conditions? If you have another camera body or lens, can the problem be reproduced with a different combination?
If it can be reproduced with a different lens, then the contacts (found around the edge of the lens socket) may in fact need to be cleaned on either the lens or the body or there may be an electrical problem with the camera or lens.
Clean the contacts with a microfiber cloth. They are located on the back of the lens and just inside the lens mount ring on the front of the camera. If that doesn't help, try swapping the battery in your 1100D.
This may or may not solve your problem.
