Hi Rose,
Thanks for your reply on this.
We have managed to set up theme after installing the core plugin.
However, we have issues in the Footer section update. We can see it is coming from the Static Blocks back end options https://prnt.sc/fQox_PsDAx91 , so we tried to change the phone number, email address etc https://prnt.sc/GZbWAQpPm7Hc but it was not reflecting in the front end website. https://prnt.sc/kKndEqoiqU29
