Hello, I’m having a trouble accessing my website since installing code (script) on my website :
You don’t have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
My website is : https://winstema.fr
I’ve installed wordpress plugin and got this error and desactivated it. I insert the script in the tag but still the same error.
Can you help me please ?
Many thanks
Help help please, I’m still stuck with this…
I really want this to work
This seems to be unrelated issue to the plugin (especially that you deactivated it). Please check with your service provider where you host WordPress.
Yes but no. When I deactivated the plugin, the site went back online. Not working now since I added the script. If I remove it (I will do this now, I only let everything that way so that someone didn’t just walk through and say that the site is ok), everything will be back to normal.
So how do I add the script (plugin or not) and keep my site working please?
If Piwik PRO WordPress plugin in some reasons is not working properly with your site, you can add script manually using a theme editor from the Administration Screens > Appearance > Editor menu in WordPress Admin, according to this instruction: Install a container (with a tracking code) | Piwik PRO help center
or use other editing files method described in: Editing Files – WordPress.org Forums
That’s exactly what I did, let me simplify this 
With Piwik WP Plugin : 403 Error
Without Piwik WP Plugin : Site ok
With script added manually : 403 Error
Without script : site ok
Maybe I’m missing something but I take my time to do things as precisely as possible…
That’s why I thought there’s something wrong or maybe a plugin on my site causing interference with Piwik Pro Script ?
I’ll try deactivating all plugins and reactivate 1 by 1 and I’ll come here for an update, thanks for your time.
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:
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.
