Thanks stuatwider for the reply.
I found the line which you have mentioned but changing it did not solve the problem or might be I dint do it the right way.
I changed the below line from:
if ( ! function_exists( ‘heatmapthemead_posted_on’ ) ) :
To:
if ( ! function_exists( ‘heatmapthemead_posted_on_date_updated’ ) ) :
& I even tried without underscores like:
if ( ! function_exists( ‘heatmapthemead_posted_on date updated’ ) ) :
None of the above fixed the problem. Please tel me how exactly am I suppose to place the code.
