I'm launching a new website called 'Musician Power' and I have an SSL certificate, however it's not fully active.
My hosting provider shares the following information below, therefore I'm looking for someone to sort this tomorrow.
If you're interested in the work, please only contact me via PPH (and not via phone or email)

I would like to advise you that reviewing the situation for the free third party Let's Encrypt SSL Certificate I noticed that it has successfully renewed and it will expire in 88 days.
The site still comes up as insecure due to having mixed content (most likely) inside its database. This means that there are some (again most likely) images which are still loading through the non-secure HTTP instead of the secure HTTPS and you or your developer would need to have this fixed by performing a Search and Replace procedure - searching for all traces of the http://musicianpower.com/ and replacing them with the secure https://musicianpower.com/ one.
I am afraid that this is something which we do not offer as a service and it can not be done from our end. Nevertheless the procedure is a standard one, for a trained developer it is not going to take more than 10 minutes to solve and resolve once and for all.
Since the site is using the WordPress CMS there are plugins dedicated to this exact search and replace procedure which will allow you to make this by yourself as well, but if you are uncertain on how to do this I would strongly recommend speaking with your developer on the matter.
