Possible Attribute Images Bug

Hello everyone. Sorry if this has been posted before. I searched everywhere, but could not locate the issue.

Problem I'm having with new 1.5.5a upgraded to 1.5.5b installation, attribute images aren't showing at all, no matter which template is selected. Images are on server and can be viewed publicly, however the do not display on the product's page at all. I've tried using Dropdown and radio buttons, nothing seems to work.

Pluggins installed are:
Admin login as customer
Admin notes advanced
Average product rating
Ceon Manual Card
Monthly Sales & Tax
USPS 2016 0107 K8
TY Package Tracker
Zen Colorbox

Attributes Settings are as follows:
Enable Downloads - true
Download by Redirect - true
Download by streaming - false
Download Expiration (Number of Days) - 7
Number of Downloads Allowed - Per Product - 5
Downloads Controller Update Status Value - 4

Any help in figuring this out would be appreciated.

Seems your attribute images are showing fine: http://www.krappinterior.com/index.php?main_page=product_info&cPath=1&products_id=5

Now, viewing your site from a mobile device, that's a different issue. Had to enable desktop mode to really see anything on the site. Didn't really have any css displayed while on the product_info page. Navigating the categories was okay, but once a product was selected things didn't work while in "mobile" mode.

Dr Byte, thank you for checking it out. I turned everything off a few times and back on. It seems that did the trick (?), even though I tried it before and wasn't working. I wonder if something else might be happening.

@mc12345678 Thank you for letting me know! I'm using the column layout grid plugin. That's gotta be the one messing things up. Is there any other grid type of plugin that would work with the responsive classic?

I'm going out on a limb with this because I haven't deeply reviewed the front side of the default responsive classic performance, but in times past it didn't seem like the grid layout affected the actual product page just the page(s) leading up to it. Ie. Allowing product in a category to be seen in rows instead of one row per product. Been a while since I've had the need to meddle with it.

I say this because I didn't have a problem navigating the rest of the site, just when I followed the link DrByte kindly provided I was surprised to see a non-formatted listing of the menu, then two of the lower images presented at the bottom stacked on each other. I decided to try one of the category links and low and behold the site displayed. Back to a product and broke again...

I'm not so sure that there is a problem with that plugin when "properly" incorporated with ZC 1.5.5. There may have been something not correctly incorporated to take advantage of its added features but leaving the default operation as it should be.
