I have top and left side menu for my products. They are the same pages but somehow the url shows differently.
For example, from top menu, it goes to correct url https://xxx/products/PNA_oligo.htm.
From left menu, it goes to https://xxx/PNA%20peptide%20nucleic%20a ... _oligo.htm instead.
They show exactly same content.
What am I supposed to do to fix it?
I don't think anything has been changed in my web site so I do not know what is going on.
Please let me know if you have any suggestion.
Thanks a lot!
