shop problem

[honeybeads44491]

hello

i have previously opened a support thread on this topic but after the initial response - which did not yield a fix - i have not had any further feedback. so i am writing again in the hope of a resolution:

i have been setting up a website using wordpress and i am trying to put a shop in it using dukapress

i have managed to get a product working OK on this page:
http://honeybeads.x10.mx/wp/products/glass-beads-030/

but when trying to add more they seem to never work e.g.:
http://honeybeads.x10.mx/wp/products/glass-beads-042/

looking through the FAQ on dukapress' website they suggest that there may be a problem if the cache folder is not writable (i have checked this and it is 755) or that the webhost may have a problem using 'timthumb'

do you allow timthumb? should this be a problem? can i use dukapress OK with your servers? or do you recommend a different plugin for shopfronts?

thank you very much
