I spent a lot of time to integrate piwik into TYPO3. But Piwik 1.5 seems to use either
top.location.href="..." or target="_top"
to enforce that piwik is not loaded in a frame.
This way the TYPO3 Backend is unloaded, while piwik loads in the top frame.
This behaviour is found on the settingspage. Please remove the following snippet!
Thanks in advice.
Kay: this is part of the anti-clickjacking code. So, I can't remove it. However, it is configureable, albeit secure by default. If you want to frame logins or settings, you can set enabled_framed_logins = 0 and enable_framed_settings = 0, respectively. (See config/global.ini.php.)
Typo correction: I meant you have to set to = 1 to enable framing.
