Hello pavit,
They just answered me from Solidres and i believe this template needs some update:
"Hi,
It is because you are using an out of date template which does not support latest Solidres version.
To fix it, you should go to Solidres System Info page, scroll to the template override section, then disable all of their template override and try again.
You should request our template developer to update their out of date template so that it is compatible with latest Solidres version.
Regards,
