To get STS to work with this great contribution i did this:
open: /catalog/includes/sts_display_output.php
find echo "<title>" . TITLE . "</title>";
** should be around line 159 or so.
replace it with this:
require(DIR_WS_INCLUDES . 'meta_tags.php');
Then on your index.php and product_info.php pages just complete remove your standard osc <title><?php echo TITLE; ?></title> or the one that was added in this contribution. What you are doing is removing all instances of <title> and </title> from index.php and product_info.php
The only issue i have is that my product_info.php page is showing a - - at the end of the title.
My other pages like the contact page ect are just displaying the normal site title.
