I have checked and reset the password, its working.
My queries here again:
The problem was gone when I deactivated envira gallery but anyhow i update the debug code as you said and activated the envira gallery, the error reappeared.
I have made the new header which is working but the footer is overlapping this new header. Its sticky header so when browsing until down, sublink will go under footer and invisible.
The other problem is I am using one-page anchors, so all menu item is highlighed color and also when I press Home on the menu it try to reopen the page which i believe should ignore when I am on the same page.
Your help is appreciated. Login details in the secure note.
