mixed content for p01-contact

[karin9nona]

I'm helping someone with their get-simple website, normally I'm a WordPress user. 

I installed a let's encrypt certificate, changed the website basis URL to https, added to .htaccess. All pages of the website are https now, except the page with a p01-contact form. There I have mixed content, I get this error in the console:

Mixed Content: The page at 'https://bradom.be/contact/' was loaded over HTTPS, but requested an insecure stylesheet 'http://bradom.beplugins/p01-contact/style.css'.

I installed the force HTTPS plugin, but that doesn't solve the problem.

What can I try next? Thanks!

Hi,
The mixed content message is well known.
It is not really a problem but simply somewhere in your website
a leftover url that needs to be changed from http to https.

First, you can try Carlos plugin to fix it. This plugin is meant to be used
to migrate a website to a domain with a new url. Since your old url starts
with http and your new url starts with https you can use this plugin also
in this case.

If that does not work then second, open all files from the p01-contact plugin
in an editor and update the URls in these files using search - replace ...
so let the editor search for http and replace it with https

Thanks a lot! Found the http in the plugin files and replaced it with https. Solved
