Fixing Gutenberg White Screen on GoDaddy

If you’re using WordPress with the Gutenberg editor on GoDaddy hosting and encountering a white screen or infinite loading when trying to add or edit posts, the issue might be related to GoDaddy’s server settings trimming large responses.

The Issue:

• Gutenberg preloads a lot of content, especially when using a premium theme with extensive settings.
• GoDaddy’s server settings trim long response lines, breaking the data required for the editor to function correctly.
• This issue does not appear with the Classic Editor, as it loads fewer settings in comparison.

The Solution:

Adding the following directive to your .htaccess file can fix the issue:

<IfModule mod_substitute.c>
SubstituteMaxLineLength 10m
</IfModule>

This increases the maximum line length GoDaddy’s server will process before truncating, allowing Gutenberg to load correctly.

Steps to Apply the Fix:

1. Edit your .htaccess file (found in your WordPress root directory).
2. Add the above code snippet at the end of the file.
3. Save the file and clear your cache.

After applying this fix, Gutenberg should load properly without the white screen or endless loading issue. If you’re still facing issues, consider switching to the Classic Editor or reaching out to GoDaddy support.
