Hello. We installed from the new quickstart package to the domain (see info)
However, the template version of the included/installed template is v1.0.0 instead of v2.0.0.
Moreover, when trying to manual update/reinstall v2.0.0 through the backend, a main error keeps poping up that the component.php file is not included int the SJ_Kay_sj_kay_template_j3.x_v2.0.0 file and stops the installation.

Please advise with necessary steps for a proper template update.
Thank you for your quick response.

Dear
Please install latest version: sj_kay_quickstart_j3.6_v2.0.0.zip

About template version, we missed change version to 2.0.0 in template xml file
You can go to templates\sj_kay\templateDetails.xml and change to:
<version>2.0.0</version>

Thanks
