I have herd this crock from shapeways emploies many times. Throughing the code up on a server and testing to see there are no compile errors is not testing. You need to make beta.shapeways.com purge all caches after upload and tell us to help with the testing. You
NEED to do this for several reasons:
1) Your emploies have no sense of reallity and think that form is more important the function
2) Your emploies are incompitant and can't run simple testing procedures like using fire box to find javascript and css errors.
3) There are lots of us and we can tell you what works, what doesn't, help find bugs, and even give ideas how to fix.
Putting changes up like this without testing(what you do is not actually testing) first effects everyone. You waist our time since we can't get things done efficiently. And you effect our customers because they can't necisarily find things or they don't see the description. This means reduced sales which means less money for everyone.
Write up a real testing procedure. Don't relie on your employes to remember every step. And here are a few things to put in it:
1) Upload to internal test server
2) Clear all caches
3) Check with firebug and other testing sweets for any errors
4) Check visual appreance and functionality of sight in landscape and portraight
4.1) Firefox
4.2) Internet Explorer
4.3) Crome
4.4) Safari
4.5) Opera
4.6) Blackberry
4.7) Ipad
5) Fix all problems and go back to 1 if there were any
6) Upload to beta.shapeways.com and email all shop owners of new beta
7) Clear all caches
Fix all bugs found by us and go back to 6 if there were any
9) Upload to main site.
