Thread:Project:Support desk/Cannot upload docx files

Version Mediawiki 1.15.4 (on my computer) PHP	5.3.0 (apache2handler)

Hi I have recently updated from Microsoft Office 2003 to Office 2013. I am now unable to upload docx files. I have added docx to Local Settings. when I attempt to upload a docx file I can see that docx files are permitted: Permitted file types: png, gif, jpg, jpeg, docx, pdf, doc, xls, ppt.

However why I try I get the message: Cannot upload this file because Internet Explorer would detect it as "application/zip", which is a disallowed and potentially dangerous file type.

I checked on the MediaWiki extensions page and as suggested added: $wgAllowJavaUploads = true;

But that did not make any difference. I have a feeling that this maybe because I am running an old version of MediaWiki!

Thank you for any assistance.
