Hello Fam,
My problem is solved; here is what I did base on your inputs:
1-Uninstalled both Chrome and Firefox then after reinstalling, I installed the extension once again. Firefox worked straight away after this whereas I did few more things to get it work in chrome.
* for Chrome I had to enable the developer mode and check both "Allows access to files urls " & “Allow in incognito”.
2- Till now IE is still giving me tough time but I am sure I am doing something wrong still looking into the issue.
I attached here the screenshots of both error message and output page of what I get with IE.
Please help me interpret the message and tell me what I am missing in the process.
Thanks again to you guys for your valuable suggestions.
