Support » Plugin: Compress JPEG & PNG images » HTTP Error

  • Resolved amsgator


    When I try uploading an image (even just one) I get an “HTTP Error” in the dashboard. It seems the image is uploaded and compressed (so are the wordpress generated sizes) so I’ve got no clue what the “HTTP Error” is about.

    Sorry to hear you are experiencing issues. Do you have the most recent version of the plugin? We pushed a fix in v.2.2.2 of the plugin specifically for network errors (such as HTTP errors) as mentioned in the update change-log here: .

    Both sites are using 2.2.2.

    It doesn’t give me any info other than “HTTP error.”

    I just got the same error. How I got around it.

    1. Disabled plugin
    2. Uploaded image
    3. Activated plugin
    4. Compressed image (well, sorta..)

    As with bulk optimization, the image compressed but never told me it actually compressed…until I clicked on compress a second time.

    Does it happen with all images and does it happen all the time or is it intermittent? Also, could you perhaps try to disable all other plugins and see if the error is still there?

    It’s intermittent. Was able to upload and compress the same image with no issues.

    This just popped up again. HTTP Error.

    I then went into the media library and the images showed “compressing”. The compression never finishes.

    I can’t use this plugin as it’s currently developed. It’s just unreliable. Now, it won’t compress images at all. Just spins and spins on manual compression of A SINGLE IMAGE.

    I’ll hold off on my review for a little bit, but I cannot recommend this to anyone…and I have been.

    Sorry to hear that you are experiencing these issues! We will investigate what could cause the problems you are having and will update you when we know more.

    Thank you for your patience!

    @tinypng there are no errors logged in my cPanel, so I can’t give any more details than an “HTTP Error.” I wish I had more to give

    I just disabled all plugins except TinyPNG and it still throws the HTTP error. It appears to be compressing the images, but within the dashboard it does not show thumbnail on the media page, making it essentially useless. Guess I’m restoring from a backup so I have my thumbnails back.

    I am having exactly the same problem. Any progress on resolving the issue

    Not yet, but we’ll keep this thread informed.

    status; Latest error: Credentials are invalid (HTTP 401/Unauthorized)

    what is the problem ?

    okay okay, i’m sorry. i not completed mail account 😀 working this plugin.

    Hi we have also experienced this issue on our site too.
    Hopefully these notes provide a bit more clarity on where the issue may possibly be coming from:
    1. We use it on a multisite
    2. HTTP error only appears when uploading directly in the post or the media library
    3. As an admin, I didn’t see the error in media library (but editor roles did)
    3. Uploading images in the media library never finishes the loading icon and results

    Hopefully this issue can be resolved soon, as we hope to use your paid service for our large WordPress site, thanks!
