Jquery error profile update does not work

[usaipcg]

When I try to update the profile inthe Affiliate I get a white page and it does not update itself:

Developer tools shows this:

I found an issue with a plugin and deactivated the plugin but when I press update it still shows an empty page and it doesnot update. It gives me now this Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Hi I traced it all back in the error log and I see this: ‘[11-Dec-2017 15:41:12 Europe/Amsterdam] PHP Warning: Cannot assign an empty string to a string offset in /home/usaipcg/public_html/baby3dprint.nl/wp-includes/class.wp-scripts.php on line 426

Your site seems to have at least 5 different versions of jquery.js installed. Please refer to the following:

Loading multiple copies of the same library not only causes plugin/theme conflict, it also slows your site down since the webpage is loading the same resource twice.

PHP errors are these

Line 426 $l10n[$key] = html_entity_decode( (string) $value, ENT_QUOTES, ‘UTF-8’);

Line 1045 $is_utf8 = in_array( get_option( ‘blog_charset’ ), array( ‘utf8’, ‘utf-8’, ‘UTF8’, ‘UTF-8’ ) );

What is the actual error message? What PHP version is your server using?
