BUG Can't access to tabs in setting after configuration

Problem occured with Piwik path (PHP API, beta) option.

Does this problem also occur using the REST API?

Which PHP and Piwik versions are you using?

Can you enable WP_DEBUG in your WordPress config file?
define('WP_DEBUG', true);
Maybe you will get some error messages.

REST API works fine. I will try debug

With debug in piwik settings tabs

by the way thanks a lot for your answer

Are you using a second plugin connecting to Piwik?

Otherwise WP-Piwik seems to call the Piwik constant definition twice… I’ll check this.

Are you using the toolbar widget? Can you try to disable it?

You are right I must test all the plugins… On my other blog it’s working…

I come back to you when i find the problematic plugin

WP Review is the problematic plugin

Does this plugin use Piwik or some WP-Piwik functionality? Can you give me a brief description?

Maybe there is a way to avoid the potential conflict.

No it does’nt, it’s a plugin build by MyThemeShop for a theme.
Here is the description :

“WP Review plugin is an easy yet powerful way to review content easily, without affecting the speed of your site. If you’re a blogger, you probably occasionally review or rank products, services, tools, recipes, or other content on your site. WP Review plugin is a customizable and lightweight way to create reviews, using stars, percentage or point rating, and it includes support for translation, WPMU, Google rich snippets and unlimited colors. Just install it and follow the simple configuration instructions to place it in your desired location.”

Hello,

I have the same issue with my own WordPress Network when I use WP-Piwik in PHP mode. I try per website config and network wide configuration. Both mode give the same result text/plain content-type instead of text/html.

I try to desactivate every plugin to find wich plugin is problematic and I have the same result. I will try to find why later (it might be a network plugin).

Regards.
