What is this error??

Permalink
Hi,

When I tried to change the color of the navbar (design --> color picker) I went to publish the site and got this error:

Warning: Cannot modify header information - headers already sent by (output started at public_html/packages/asmiller_gallery/blocks/asmiller_gallery/controller.php:323) in /home6/motorpro/public_html/updates/concrete5.4.1.1/concrete/startup/process.php on line 466

The color change did not show up, but when I go in to edit again, the color picker is set to that value.

Seems like it's colliding with the gallery block or something?

I recently updated to the new version.

Any suggestions greatly appreciated.

Thanks!

Andrey

It looks like you have a package which is writing something out to the browser before concrete5 is writing something else out which needs to be written out first (a bit simplified...).

If you open up and "view source" you should see what the package is writing out... it might be an error message, which could help you fix it.

It would also be helpful to see what line causes the text to be written out. Oddly, though, I downloaded the package (Gallery) and looked at the supposedly offending file, and it doesn't have nearly as many lines as your error message indicates. Usually lines don't shrink in later versions, but you might want to confirm you have the most recent version (2.0).
