Problem with Crossref in OJS 3.0.2


I am facing a problem in Crossref plugin after upgrading from OJS 3.0.1. I have the following error message after clicking submit for any article:

Warning: htmlspecialchars() [function.htmlspecialchars]: charset `UTF=8' not supported, assuming iso-8859-1 in /home/content/29/7935229/html/plugins/importexport/crossref/filter/ on line 113

Warning: Cannot modify header information - headers already sent by (output started at /home/content/29/7935229/html/plugins/importexport/crossref/filter/ in /home/content/29/7935229/html/lib/pkp/classes/core/ on line 99

I wish to find a solution for this issue. Thanks
