Plugin Conflict - Really Hard to Isolate - Why?

Hello: I am building a new site and have just connected Piwik to this new site. The site was functioning well until I implemented Piwik.

ERROR: Error: Invalid XML: [{“src”:“",“full”:“”,"id”:1360}]

I am trying to isolate why Piwik would interfere and throwing this error. I have gone through many troubleshooting steps but I am coming up with nothing tangible other than to say Piwik in conflict here. The server error logs are not capturing this error either???

Further: When I change the tracking code setting from manual entry to default Piwik throws this error:

Fatal error: Call to undefined function WP_Piwik\is_user_logged_in() in /home/proje485/public_html/ on line 70

Fatal error: Uncaught exception ‘Zend_Session_Exception’ with message ‘Session must be started before any output has been sent to the browser; output started in /home/proje485/public_html/’ in /home/proje485/public_html/ Stack trace: #0 /home/proje485/public_html/ Zend_Session::start(true) #1 /home/proje485/public_html/ Zend_Session_Namespace->__construct(‘CorePluginsAdmi…’, false) #2 /home/proje485/public_html/ Piwik\Session\SessionNamespace->__construct(‘CorePluginsAdmi…’) #3 /home/proje485/public_html/ Piwik\Nonce::getNonce(‘CorePluginsAdmi…’) #4 [internal function]: Piwik\Plugins\CorePluginsAdmin\Controller->safemode(Array) #5 /home/proje485/ in /home/proje485/public_html/ on line 443

Since the error occurs on file uploading it is pretty disruptive.

Any ideas?

Thanks Rich

Hello Richard

make sure you uploaded all files correctly from the WP-Piwik plugin. After you try to re-upload if you still have a problem, ask in the WP-Piwik plugin forum.
