Warning: Cannot modify header information – headers already sent by (output star

Getting this error now…

Only happens when you try and add a post or edit a post.

My wife sees it sitewide on the admin area, I only see it after update post or publish post…

Warning: Cannot modify header information – headers already sent by (output started at /home/save5478/public_html/wp-content/themes/salv5/includes/td_config.php:1) in /home/save5478/public_html/wp-admin/post.php on line 236

Only changes i’ve done to the config file is add the ability of 5 more custom ad spots.

Reverting back to a backup from yesterday.

I checked my error log and these are all the errors we have logged since theme installation:

I noticed these errors when using the custom page builder. Modifying settings such as responsiveness / design options.

Restored, compared files and found what I did… total brain fart and this is what caused the issue:

‘custom_ad_5’ => ‘custom_ad_6’,
‘custom_ad_5’ => ‘custom_ad_7’,
‘custom_ad_5’ => ‘custom_ad_8’,
‘custom_ad_5’ => ‘custom_ad_9’,
‘custom_ad_5’ => ‘custom_ad_10’

I forgot to change the other numbers lol Totally over looked it last night, was late. Even overlooked it this morning otherwise restoration wouldn’t have taken place 😉

I still receive errors within Custom Page Builder though.

I will capture a screeny next time I see it.
