This is how the HTML of the page ends:

<div class="pageWrap" id="multisites">
    <div id="main">
        <div piwik-multisites-dashboard
             class="centerLargeDiv"
             display-revenue-column="true"
             page-size="50"
             show-sparklines="true"
             date-sparkline="2014-04-07,2014-05-06"
             auto-refresh-today-report="300">
        </div>
    </div>
</div>
    </div>

    </body>
</html>

Can also provide a screenshot and any other debugging info as needed.

Hi chris,

which browser are you using? Can you try to delete all files within the 'piwik/tmp/assets' directory? Is it maybe possible to provide us a login for your Piwik instance? View permission should be enough. This would help us debugging this issue. If so, please send us an email to hello@piwik.org and leave a comment here in case it goes into the spam folder

Replying to tsteur:

which browser are you using?

It's the same in Firefox 29.0, Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0, and Debian Chromium 34.0.1847.132 Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.132 Safari/537.36.

Can you try to delete all files within the 'piwik/tmp/assets' directory?

Yes, that didn't make any difference.

Is it maybe possible to provide us a login for your Piwik instance? View permission should be enough.

I have asked the client this question, I expect it'll be fine.

Have done, sent with these email headers, hope you can find it:

Thx again Chris!

So for other people having the same problem, the issue is the following:

Files to those HTML files were blocked by the webserver:

/plugins/MultiSites/angularjs/dashboard/dashboard.html
/plugins/CoreHome/angularjs/siteselector/siteselector.html?cb=8c07843a982258284632854e69fa9ffd
/plugins/Feedback/angularjs/ratefeature/ratefeature.html?cb=8c07843a982258284632854e69fa9ffd

Please whitelist *.html files within the plugin folder.

Waiting for further feedback, see email.

Thanks for debugging this!

The Nginx config for Piwik, which I put together a couple of years ago contains:

## Disallow access to several helper files.
        location ~* \.(?:bat|html?|git|ini|sh|svn[^.]*|txt|tpl|xml)$ {
        return 404;
}

Which is clearly the cause of the problem. This config was copied from the suggested configuration here https://github.com/perusio/piwik-nginx/blob/master/apps/piwik/piwik.conf which contains:

    ## Disallow access to several helper files.
    location ~* \.(?:bat|html?|git|ini|sh|svn[^.]*|txt|tpl|xml)$ {
        return 404;
    }

I have commented out that section of the config and everything is working fine, feel free to close this ticket!

Is there a best practice Nginx config you can suggest?

Thanks again for your help.

Hi Chris,

I've made a pull request on the nginx configuration to account for the
HTML files:
https://github.com/perusio/piwik-nginx/pull/19/files

Could you please try this patch and confirm that it works for you? btw
if you can comment on the pull request, that would help too.

This matter can also be solved by editing the regex as per https://github.com/perusio/piwik-nginx/pull/19/files

## Disallow access to several helper files.
        location ~* \.(?:bat|git|ini|sh|svn[^.]*|txt|tpl|xml)$ {
        return 404;
}

I can confirm that this solves the problem and have posted a comment here matomo-org/matomo-nginx#19

Thanks again for helping solve this so fast!

You're welcome!
