I went to
Design/blocks to choose the new and altered banners... but got this error:

Fatal error: Class 'AJson' not found in /home3/writeblo/public_html/yoglin/store/extensions/banner_manager/admin/controller/responses/listing_grid/banner_manager.php on line 299

do I have the images in the  wrong place?
also the pics are not lined up properly. how do I change the alignment of them if I need to move them over or to the other side of the banner space?
