If your Photo Cart is suddenly getting a 500 error or only displaying a blank page then you or your hosting company has updated the PHP (programming language) to PHP 7 which Photo Cart is not compatible with (and will not be compatible with) mainly because of the removal of the my_sql functions which are replaced with my_sqli functions.
I can't figure out how to change my "rollover" color on my cart. My cart icons are green and the text is white. When I "rollover" the link the text turns yellow and it's very difficult to read. Image attached. Thank you in advance for your help!
