Get error blocked by client

Hi! I am new using Piwik pro.
I just created a new Consent manager, and my plan was to display this in one WordPress playground.
I followed the steps, and installed the Piwik. pro plugin. Activated the container.
But I don’t get the Window at my site. And I get at the console this error:
https://igniclean.piwik.pro/c96ca04d-d1fc-410b-abc2-ebcf90e2aa9d.js net::ERR_BLOCKED_BY_CLIENT
It looks like my default browser settings (Chrome) block the piwik code.

The playground is here:
https://igniclean.wp4.wp-hosting.no/

I tried also with the script at the body, but I got the same result.

If somebody knows how to resolve this basic problem.

Hi @Mariana!

Some browsers (or their particular settings) or browser extensions block the entire Piwik PRO container, so it doesn’t load at all. The easisest way is to disable the blocking mechanism.

I see.
Thanks for your answer.

For people still looking for a solution. I had the same issue (403 server errors after the first pageload). The issue was the Web Application Firewall (= WAF), which you can configure in Plesk.

If you check the Modsecurity log file (there should be a link on the WAF page) you will find the firewall is triggered by the Piwik cookies for some reason. You need to look up the ID’s of the rules that are triggering the blocking by searching for id " .

In my case, the rules that were an issue were the following ones:

  • 942260
  • 942200
  • 942340
  • 942370

I added those numbers in the field “security rule ID’s” in the section “switch off security rules”. After that I saved the settings, removed all cookies from my browser and refreshed my site: everything works as expected now.

Hopefully I can save some people some headaches this way.

This should be documented somewhere in the Piwik Pro documentation really, because in my search for a solution I’ve seen a ton of people with this issue.
