Hi @properlypurple. They’re setup as default:

• Thumbnail size (150 x 150 pixels)
• Medium size (maximum 300 x 300 pixels)
• Large size (maximum 1024 x 1024 pixels)

Thank you for your help.

Hi @jordesign. I tried that, and I also disabled the SiteGround cache while regenerating. It didn’t fix the issue.

Hi @mrfoxtalbot,

Changing the theme to Twenty Seventeen fixes the issue! (Screenshot: https://i.postimg.cc/FRmZ9Cmq/Screenshot-2023-07-19-at-10-16-34-PM.png).

I regenerated thumbnails. Then returned to Twenty Twenty. Same issue.

Hi @jordesign,

I removed the featured image, then updated the post and ensured it was gone. Then I went to set the featured image again, when I clicked to set the featured image it was still showing that the original featured image was selected! So I set the same image. But it still remains 150x150px on the post.

When I set a new and different featured image, it works as normal. Normal featured image size. But when I go to change that featured image, it’s again showing me that the original motorcycle featured image is selected! Not the new one I set.

The only way I can fix the featured image is by downloading the image, re-uploading it and then setting it as a featured image.

Sorry, I know it’s confusing! I wish I could somehow remove the 150×150 resize being put on some of my featured images.

Hey @jordesign, I did have another theme installed before. But the featured images were never 150×150. I guess something happened when I changed themes.

I regenerated thumbnails and cleared the cache. Same issue.

The only way to fix it is for me to go through every post like this and download the featured image, re-upload it with a different file name, and apply it as the featured image. That fixes it. But it will be a slow process.

Thanks for your help. I deactivated Jetpack and cleared the site’s cache. Same issue.

The correct full-size featured image is set on the post. But for some reason, WordPress is changing the featured image to a 150×150 jpg image when serving it.

Hi, they’ve been showing as thumbnails ever since I changed to Twenty Twenty theme.

My site and plugins are all up-to-date.

I turned disabled all plugins, but the problem remained.

Do I need to hire a developer to look into this?
