Explains the devaluation in my crypto 
I’m not able to replicate this at my end with the URL: https://../slpw/sitelokpw.php?sitelokaction=logout&page=https://www.mywebsite.com/logout/index.php
Blocs doesn’t do anything to the URL, it is left intact with no https being replaced by http.
Can you check the actual source code in a code editor to make sure this is not some kind of server rewrite doing this once the browser parses it?
It you are getting this in the actual source code in a code editor, then I’ll likely need a copy of the project file as its not a straight forward issue and potentially has a bunch of other factors that cause it.
Any chance you can send me a copy of this project please?
