//*note: problem solved// I'm using uptheme option panel for typography. I'm new in PHP and I'm getting this error:
NOTICE: wp-content/themes/XXXX/admin/library/engines/typography-engine.php:74 - Undefined index:
Line 74 contain this code:
$stylesheet = $up_fonts[$font]['style'];
I've read answers to similar questions but I've been unable to find a solution for my error. Please help. Thank you for taking your time to answer.
Clearly from the error can be read that the current index you are using for the array doesn't exist.
$up_fonts[$font]['style'] is not set.
You haven't defined your array enough. Check if the value exist with
if (isset($up_fonts[$font]['style'])):
$stylesheet = $up_fonts[$font]['style'];
endif;
