Hi Wayan. I actually finally worked around the problem by using a previously saved date of the site and changing some page titles and material on them. For some unfathomable reason that I couldn't determine, it was titling 3 pages the same in the H1's - despite them being different pages. I would change one, and the other two would change. I want round with it for about 5 hours last night.
You need to release the H1 from being a Symbol.
A symbol?
