Error index.php on line 64 & jQuery.ajax – version 2.24.1

[LS]

Hi! After upgrade to 2.24.1 appears this error message on admin dashboard:

“Warning: file_get_contents(http://userproplugin.com/userpro/userpro_notifier.xml): failed to open stream: no suitable wrapper could be found in *****/wp-content/plugins/userpro/index.php on line 64”

Also, we can’t edit profiles, appears this error message after click on ‘Edit profile’:

“Error in jQuery.ajax while submitting a form:SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data”.

Also, we are having same jQuery.ajax error trying to login from frontend.
