[Resolved] Keep getting error messages about theme-functions.php

[Lola]

Hello,

I keep getting error messages about the theme-functions.php

Warning: Cannot modify header information – headers already sent by (output started at /home1/mistresslola/public_html/wp-content/themes/generatepress/inc/theme-functions.php:1) in…

over the past hour it’s been giving me lots of different files after that.

I think I may have broken the code when I inserted some I pulled from the net (stupid I know, lesson learned). I gained access again through FTP and deleted what I added, and now it keeps giving me this error 🙁

I’ve disabled all my plugin’s through FTP (and only re-enabled the ones I need for my site to continue running whilst I figure this out, which were all running fine before my silly editing)

I’d be so grateful if you could have a look and see if you know what’s causing this.

Hi there,

Best thing to do is replace the contents of that file with the default code: https://themes.svn.wordpress.org/generatepress/2.0.2/inc/theme-functions.php

Then use one of these methods to add your own PHP snippets: https://docs.generatepress.com/article/adding-php/

Let me know if this helps or not 🙂

Hello!

I updated that using FTP and now I’m getting these error messages when I try to log in:

It may be a good idea to re-upload all of the theme files via FTP, in case anything else was changed in there.

Seems to have done the trick, thanks!

No problem! 🙂
