WP 6.8.2 - In the Media Library some images have an empty preview in both views.

[garrigan]

Note: This issue did not occur in the previous version.

The image is visible within "Attachment details".

The "developer tools" indicates the file size is very small. Example: 391 B, 428 B

Test environment: New installation without any changes.

I did empty the browser cache.

I have repeated the process a few times.

I can provide the images.

It should be noted that I am not an expert with WordPress. I am an unemployed IT guy who had supported on-premises Windows-based servers. The site is for my job search.

Feel free to ask for additional information.

Hi and welcome, James,

I am unable to reproduce the issue you describe. Can you please provide more details about your environment and maybe screenshots. Thank you.

[garrigan]

Site Health Info - Dev1 site

[garrigan]

I uploaded both images and a text file with the site info.

[Presskopp]

just for reference, working for me

[garrigan]

I saw your attached image. Perhaps the uploaded image files are changed by this ticket system. Does a method exist to upload the files as a zip file? I can provide access to the test environment. It is a VMware workstation snapshot.

[garrigan]

Note: Within 9-previous-wordpress-version-all-images-are-visible.png image number 30 "cement texture" is nearly the same color as the background.

The files that are 1 KB in size are blank or empty images. When I open the 1 KB files with an image viewer I do not see anything.

[audrasjb]

Hello and welcome to WordPress Core Trac,

Moving to milestone 6.8.3, pending detailed review.

I opened each 1 KB image file with a text editor.

[garrigan]

I realized it has been a while since I last imported images from an initial installation of WordPress.

It fails with 6.8 and I am successful with 6.6.

On Friday I will try each version with a fresh installation.

I will report the last successful version for which all the image files are visible.

[garrigan]

The issue does not appear within the following versions of WordPress.
6.7 good
6.7.1 good
6.7.2 good

Based on my testing, I initially see the issue within WordPress version 6.8

[garrigan]

My test environment is consistent.

I revert to the same snapshot, and I execute the same bash scripts. I only change --version=

[monikarao]

I tested this multiple times but couldn’t reproduce the issue.
OS: Mac
Browsers: Chrome and Safari

Hi,
I was also importing the images via the WordPress importer. I can create an externally accessible test environment.

[garrigan]

It has been nearly two weeks since the last update to this ticket and thus I am following up on this issue.

Based on my initial information, the internet browser is not the proximate cause of the issue.

My test environment is consistent. I revert to the same snapshot, and I execute the same bash scripts. I only change --version=

The issue does not appear within the following versions of WordPress.
6.7 good
6.7.1 good
6.7.2 good

Based on my testing, I initially see the issue within WordPress version 6.8

I provided images to illustrate the issue.

To be fair to Monica, our test environments are different. Monica: (OS: Mac) -- Me: (Rocky Linux 9.5)

I can create an externally accessible test environment without third-party plugins.

Another option could be to use some type of software to allow remote viewing of my test environment while I execute the steps to illustrate the issue.

Both options would require scheduling ...

Additional details from the current test environment are shown below. The PRODUCTION environment has different specifications.

6.8.3 was a security only release. Punting though 6.8.4 is not planned as a release

[riccardodicurti]

I tested this issue using the official Docker environment and downgraded to version 6.8 with:

wp core update --version=6.8 --force

I wasn’t able to reproduce the issue.

@garrigan, could you please confirm whether you’re also working within a Docker environment?

Ciao from WordCamp Verona

Hi, I am not working within a Docker environment.

I attached the file Site Health Info.txt when I created the ticket. It is the third attachment.

Feel free to reach out to me with additional questions or concerns.

I repeated the same test with the current version of WordPress 6.8.3. The issue exists in the current version of WordPress 6.8.3.
