Undefined array key – flowpaper.php on line 288

  • Hi,

    I saw this error in the modsecurity log:

    AH01071: Got error ‘PHP message: PHP Warning: Undefined array key 0 in /jimfg.com/httpdocs/wp-content/plugins/flowpaper-lite-pdf-flipbook/flowpaper.php on line 288’, referer: https://flowpaper.com/

    I am not very technical but does this need to be addressed? If so what do I need to do?

    Thanks, Daphne
