Hi Guido

Thank you for your reply.
I am not a developer, so I am not quite sure what you are asking.

It probably is a portion of code. I am trying to locate it so I can fix it from http: to https:

I got this line of code from using whynopadlock.com.

https://www.whynopadlock.com/results/f159a44a-5225-4fc1-8af0-68dc6b314fcf

There was a similar line of code relating to google fonts in the style.css of my theme (https://fonts.googleapis.com/css) which I fixed.

Previously, on a different site I moved to SSL, There was a line of code as follows in the Mailchimp widget:
https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js

I have removed the MailChimp widget from my site, but still it is insecure.

I fixed all the other http: issues using another search and replace plugin (Better Search & Replace) as I couldn’t get Search & Replace to activate.

This is the string in the URL when the error message ‘This plugin can not be activated because it requires at least PHP version 5.4.0.’ appears:
https://www.highland-personal-development-photography-tours.com/wp-admin/plugins.php?action=activate&plugin=search-and-replace%2Finpsyde-search-replace.php&plugin_status=all&paged=1&s&_wpnonce=330773d5b1

Here is the error when I look at the source code in Chrome:

Mixed Content: The page at ‘https://www.highland-personal-development-photography-tours.com/’ was loaded over HTTPS, but requested an insecure script ‘https://maps.googleapis.com/maps/api/js?sensor=true&ver=4.9.2’. This request has been blocked; the content must be served over HTTPS.

I am not sure how/what tool I need to do to track down what is generating the line of insecure code.

Do you have any suggestions?

Thanks

PS. I have one more WordPress installation to add to my hosting package, for a new blog/site with a new URL. This I will need to add to a subfolder. I don’t want to end up in the same situation….
