Could you check this link?
On the right side there is search form and for "Cena" (That is Price for artical, on Serbian) there are 3 tags. One of them is unexisting, "5310", and I am wonder how to remove it. Through dashboard option Post Tags I could find no even one tag even if I set in Screen Options to show 999 tags.
What am I supposed to do?
Thanks in advance, kind regards.
