SSL

This is the cause:

Mixed Content: The page at ‘https://www.archerydistrict.com/’ was loaded over HTTPS, but requested an insecure image ‘https://www.archerydistrict.com/wp-content/uploads/2016/03/AD-Logo-02-01.png’. This content should also be served over HTTPS.

Using the plugin “better search replace”, search for https://www.archerydistrict.com and replace with https://www.archerydistrict.com.

Afterwards, clear your Lightspeed cache.

Hi, just tried that but i’m getting error 502 and site is down.

Via PHPMYADMIN, please look at the site_url row of your wp_options table. What is the value for that key?

The value is “https://www.archerydistrict.com”. Should I change that to “http” instead of “https”?

It appears you do not have an SSL certificate installed. Contact your host.

Agree with Steve. I did not find a valid SSL Certificate on your website.
Please add SSL Certificate and if again check error I recommend to use SSL Checker tool to find error.
