fullpage.js報如下錯的解決辦法

控制台報錯：fullPage: Fullpage.js version 3 has changed its license to GPLv3 and it requires a `licenseKey` option. Read about it here:

解決辦法：

在fullpage.js文件中查找licenseKey，刪除如下代碼

if(!isOK){
　　showError('error', 'Fullpage.js version 3 has changed its license to GPLv3 and it requires a `licenseKey` option. Read about it here:');
　　showError('error', 'https://github.com/alvarotrigo/fullPage.js#options.');
}

刪除后將下一行的else也刪掉，變成如下代碼
if(l && l.length < 20){
　　console.warn('%c This website was made using fullPage.js slider. More info on the following website:', msgStyle);
　　console.warn('%c https://alvarotrigo.com/fullPage/', msgStyle);
}
