Warning: Cannot modify header information

I setup Beaver Builder on a client site: http://cleancommunicationconsulting.com/

I am able to view the “coming soon” home page. I have “The Ultimate Coming Soon Page” plugin running. But I’m not able to access wp/admin so I can log-in and make website changes.

This is the error I am receiving.
“Warning: Cannot modify header information - headers already sent by (output started at /home/cleancom/public_html/wp-content/plugins/bb-plugin/classes/class-fl-builder-admin.php:1) in /home/cleancom/public_html/wp-includes/pluggable.php on line 1196”

Looks like this --> http://screencast.com/t/40cy8oxH

With this error, I cannot log in and change the site in any way. I don’t know what to do. I’m stuck.

There is a similar thread I found, but I’m unable to understand if a fix was discovered.

I would appreciate any help you can offer.

Hey Alzay,

Sorry to hear about the problem. Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each plugin individually until you find the cause. Let us know how it goes!

Thanks!

Hey KC, my client is going to send me some additional info so I can repair their site. However, I found the same issue on a current (test) site of my own. http://play.covetedconsultant.com/

I followed the instructions you sent. For whatever reason, manually resetting the plug-ins didn’t allow me access to log in. I had to manually reset the theme.

I turned the Beaver Builder theme back on. Things seemed fine, but once I activated ANY of the plug-ins I got this error - http://screencast.com/t/Rc8FltBnT9E

This is what the warning says:

Should I re-install the Beaver Builder theme? Let me know what the next step should be…

Hey Alzay,

One thing I noticed on the video was that the BB Page Builder was outdated, do you mind getting the latest version from our site under Account > Downloads & Orders, delete the one you have currently then install the latest version? Can you do the same for the theme as well? Do you have a backup for this site?

Ben & KC, per Ben’s instructions I reinstalled/updated both the BB plugin and theme. It looks like things are back in order on my test site. (What a simple solution…probably should have done that first…sheesh.)

When I get the info I need from my client I will do the same there too.

Thanks for responding so quickly!

No worries! Glad it was that simple. Have fun with BB! :slight_smile:
