Iframe creates an w3c validation error

Support & Bugs

Hello,

I’m using the iframe for opt-out and the w3c validator gives me this output:

Error Line 188, Column 118: & did not start a character reference. (& probably should have been escaped as &.)
…ce.de/piwik/index.php?module=CoreAdminHome&action=optOut&language=de">

Any idea how I can avoid it? Is it a false positive or something I or the piwik dev team can change?

Thxs and kind regards,
BC

Hello!

Yes, this is something we could fix in the Iframe code generator and display there & instead of & - please create an issue with this suggestion if that would fix the issue: https://github.com/piwik/piwik/issues
