You’re on a very old version (1.5.0)

Are you running a custom theme? Some themes such as UI.X are using a function from 1.5.9:

So you should update XF to the latest version.

I have UIX (for update too), and Core by Pixelexit

The problem is your XenForo version, it is still on 1.5.0


UI.X and Core need minimum version XenForo 1.5.9 in their new versions. It is mentioned in their theme requirements.

If you upgrade XenForo to latest (1.5.15) then try to rebuild/upgrade the theme again you should be OK.

My UIX is 1.0.10 and Xenbase for Core is 1.5.3

I mean XenForo version.

Not for UI.X
Not for XenBase

Here:

You are still on 1.5.0
Latest is 1.5.15

You must update it.

Ok, I'll wait until officially release version 2.0

Thanks
