Problems in my Web bugs to time to see the frontend

Hi, I added my site to flexicontent a section for sale and rent cars, and I have several problems.

1 - When I go to the frontend does not look good and I have to continuously update the cache to see it, and yet not always look good.

2 - When I try to add an article from the frontend is not saved.

And another question, you can not put a picture type field and that can add more fields as in other fields?

this is my mail:
