Solution:
---------
There is no vendor supplied patch for this issue.

From Vendor`s website:
"Currently, we are completely overloaded with our
running projects,
and we don't have enough time to deal with our free
products.
The further development and support of Noah's
Classifieds is therefore suspended.
Thank you for the understanding and please forgive us
that we don't responding to the emails."
