Hello,
since I moved Piwik site to https, in the Visitor log and for every action I get “Page URL not defined” while the page title is correct. If I switch back to http everything is fine.
I found another topic with the same problem ma there was no answer.
Any clue? Thank you.
Could you compare the tracking requests? You can use the browser console to get them. You can also enable tracker debug mode and check the output. See Tracking HTTP API: API Reference - Matomo Analytics (formerly Piwik Analytics) - Developer Docs - v3
I tried, this is with https enabled and all traffic redirected to https. It seems the problem is where it says WARNING: URL looks invalid and is discarded.

This is with https enabled but no forced redirection of http to https.
Looking at url, urlref and Action name I see, not an expert at all, that in this case strings are properly decoded while in the previous case they are not. Could this be the reason which leads Piwik to discard such URLs ?

Something is wrong with your redirect. The URL parameter in your redirect should be set to:
http%3A%2F%2Fitalian-directory.it%2Fstudiorocci-nuovo-studio-recensione-evento
But currently it’s:
http%253A%252F%252Fitalian-directory.it%252Fstudiorocci-nuovo-studio-recensione-evento
Thank you. The problem is I have no idea what is wrong with my redirection. I have in place this rule in htaccess:
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ Sign in - Piwik [R,L]
Do you have any idea why the URL parameter is erroneously redirected? By the way I noticed that the redirected url is the encoded version of the first.
Thank you
Update: my latest remark led me to find the NE flag for the rewrite rule:
RewriteRule ^(.*)$ Sign in - Piwik [R,NE,L]
“By default, special characters, such as & and ?, for example, will be converted to their hexcode
equivalent. Using the [NE] flag prevents that from happening.”
At first test it seems doing the trick. What do you think?
This makes sense. Hope it works now. 
Thank you for your support.
First of all, now it is working but…
1- a rewrite rule is the most common way (and suggested) to channel all traffic to https.
2- as far as I know, mod rewrite url encode query strings before redirection by default
3- you can leave encoding out with the NE flag but, is this always good?
Would not be better if piwik tracker had a flag to disable query string encoding so that mod rewrite could get it right?
Just an idea. Thank you.
