Kalium - Problem after update to kalium 1.8.9 - No portfolio post images

Hi guys,
I’ve just updated wordpress to 5.1 with Kalium 1.8.9.1.
It seems like all the images inside a portfolio have some issue with the theme or some plugin. Maybe is the slider?
It must be something to do with the Portfolio Gallery.

We have this very strange message:
"Warning: Illegal string offset ‘afc_fc_layout’ … kalium/tpls/portfolio-gallery.php on line XXX
What should i do now? Should i buy the new Kalium 2.0 with all the plugins updated for this new version? We bought Kalium on 2016.

Thank you in advance for your help.
Regards,
Alberto
