Zip File is corrupt when define( 'WP_DEBUG', true );

[matiasbenedetto]

If you have your WP_DEBUG setting activated the resulting zip file is corrupted.

How to reproduce

1. in your wp-config.php file look for WP_DEBUG setting and set it as true: define( 'WP_DEBUG', true );
2. Export a theme using the plugin
3. Try to open the exported zip file

Thanks for the observation. More specifically, unzip command outputs the following error:

End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive.

Interestingly, I just had the case when setting WP_DEBUG to false in wp-config.php only worked partially – most error messages (deprecations from PHP 8.1) were gone, but 4 remained stubbornly, and the zip file export failed (on MacOS).

Commenting out the WP_DEBUG line altogether fixed it.

just run in exactly this issues! for me it worked with define('WP_DEBUG', false);

• Plugin version: Latest (1.13.8)
• PHP version: 8.2.13
• Start local environment with wp-env

2

• WordPress version: 6.4.2
• Plugin version: Latest (1.13.8)
