Internet Explorer 10 - Multiple file upload - Invalid Character (secureEvalJSON) [RESOLVED]

Hey guys,

I’m getting Javascript errors right after files are uploaded, for each of them, in the multiple file upload field. Stating: SCRIPT1014: Invalid character, referencing to this script call:

var i = y.secureEvalJSON(t.response) in gravityforms.min.js.

These files are also not posted right after these errors, so they’re not saved.

Can you guys check?

Using the latest version of GF here (, without addons.

OK, there seems to be a conflict with the WPML default language slug feature. I’ll investigate.

OK solved.
