I have tried to reproduce this but couldn't. I think we pretty much do not even send a 403 when tracking. Likely you have some kind of security mod active which prevents forwarding the call to Piwik and directly blocks it. I'd recommend to ask your sys-admin / hoster or have a look at your server configuration.

OK,
Thank you for your answer!
Remind that tracking is working when I remove the apostrophe in page title. Page title which is part of the URL sent for tracking....

Yes, that's what the security mod is likely blocking, the apostrophe. Please check with your hoster / sys admin it's likely a security mod or security plugin.

Hi - I had the same type of problem. The occurrence of the word "and" in the "action_name" parameter resulted in a 403 error on GET /piwik.php.

For those who cannot resolve this via their hosting provider, the solution is to filter the page title before providing it to Matomo.

Replace the following lines in the Matomo Tracking Code:

var _paq = _paq || [];
_paq.push(['trackPageView']);

With:

var filtered_page_title = document.title.replace('to_be_filtered ',''),
    _paq = _paq || [];
_paq.push(['setDocumentTitle', filtered_page_title ]);
_paq.push(['trackPageView']);

This will remove the offending item ("to_be_filtered") from the page title before providing that title to Matomo (in my case this was the word "and").
