I am trying to set up table rates in Magento 1.6.2.0. The problem occurs when I try to upload the file with table rates (CSV-file). Then the error "Unable to list current working directory" appears and I can't go any further.
TMP, Media and Var folders have perm.777.
I have read everything there was to find on the Internet on this problem - many seem to have had this problem but I have yet to see a solution.
Note: Probably not very relevant, but I am on Unoeuro hosting on a shared serverspot.
With some extensions (Wyomind Simple Google Shopping) the error shows up when var/tmp is missing in Magento directory structure.
