Meta Box

Let me see and will get back to you soon. Today my developer just pushed another fix for select_advanced and I'm wondering if it relates to your issue.

This commit fixes it. Please try again.

Hi @Maxell, I've just pushed a fix for this on Github. Please try it. New version will be released soon.

Hi @brightcreations,

I'm still working on it. I'm having problems with JavaScript :(. It might take some days. I hope I can solve it this week.

Hi @Sinusite,

I think it's not possible for now. Using a raw PHP code requires running eval which is not recommended because of security matter :(.

Can you send me the code to check for you?

Hi Maxell, I guess the bug is from JavaScript. In the version 4.5, WordPress updates its library Underscore from 1.6.0 to 1.8.3. It's a big update and because Meta Box uses Underscore library to render template for media upload, I think the fastest way is updating the Meta Box plugin :(.
