Bitrix - the problem of upload images with 1C on the website

Online shop on Bitrix.

There was some problem with the uploading of pictures to the site.

Files are unloaded from 1C all the pictures too, but on the website pictures they are not updated.

The image that we will obnovlyaet in 1C, but on the website it stays the same after unloading. Unloading occurs every day.

Details of the skins in BOS.

Need a man who knows Bitrix, as watching three, the decision has not been invented.

Problems with the 1C definitely not.

We have two of the same discharge at two sites - on one everything unloaded and the moment, the second thats the problem
