Hello Abhishek and thank you for your efforts.
I followed your instructions and it seems like we got somewhere. First issue is resolved, but second one is not complete. Please take a look at the attachment.
I am not sure where did those "<" came from (marked green). I would prefer all of them to be ">>" as original. Also when I click on the topic title it does not bring me to the 1st page but just refreshes the current one. Can something be done with this?
I forgot to mention I am using eTech style. And lines to edit were in breadcrumbs.html not overall_header.html, in this case.
Thanks again for fast response and trying to help!
