SSL Certificate expired

I loaded the theme and it asked me to install the required plugins but when i try it gives me an error:

"Downloading install package from http://www.gavick.com/upd/gk-widget-rules.zip
Download failed. SSL certificate problem: certificate has expired

please help?

Hello,

Please just download the package and install it manually. It seems that some packages have non-SSL URLs and this causes with HSTS enabled for our domain the described issue. We will fix it in the next release.

what do you mean by upload it manually?

I put all three files into one compressed folder and uploaded it, then extracted it and this is the issue. What should i do differently?

The concern I have is: If i only upload the quick start file - it gives me an error message saying the stylesheet is missing. And no matter what i do now, whether i upload individually or together - the error about the SSL certificate keeps popping up. This website is a no-go right now for me. I really need help to resolve this as quick as possible pretty please?

Hi,

You can't install the quickstart on existing wordpress (through Appearance -> Themes) - please check the installation tutorial:
https://www.gavick.com/documentation/th ... o/install/
(Installation Options).

Regarding the plugins, please open the following URLs in your browser:
https://www.gavick.com/upd/gk-widget-rules.zip
https://www.gavick.com/upd/gk-nsp.zip
https://www.gavick.com/upd/gk-tabs.zip

and upload these packages to your wordpress plugins section (it's not necessary if you are installing the quickstart)
