Thank you mc12345678 for answering to my question, it was sent out just before RodG took over to help me.
I don't see the URL of the 2 items which cannot be open any different even after I remove all the extra log files.

Based on Rod's prognosis, it seems my problem has to do with the template I use.

So, I would like to ask what I should do next, may either you or RodG advise me what to do next? Thank you
