Doesn’t seem to work?

Hi @goody317,

Thank you for your message.

Do you use CDN and your images are on a different server than WordPress?

Hi Mateusz,

I don’t have a CDN. All images are in my hosting.

@goody317, are you sure these files are on the server? Does the server have read access rights?

Yes, of course they are on my server – they’re created by wordpress, for example:

/DSC05053.jpg
/DSC05053-780×516.jpg
/DSC05053-1920×1080.jpg

etc, how do I know if they server has read access rights? is this just for my uploads folder?

This error occurs that the file could not be read, when the is_writable function in which I pass the path to the file returns false.

Is the problem also for new files that you add to the media library? Try to add some new file and check if it has this error too.

New or old files still get the same error, I tried another plugin for WebP and it reads all of them about 16k images and it is all fine. I guess this plugin didn’t work for my website some how.

The problem concerns only some of the images, because I see that we managed to save 455MB of images weight, so a lot has been generated again. If there was a problem with access to all files then you would not have any converted files.

If the problem concerns several images, you can easily ignore it. Instead of these images will simply upload the original, and all others will work in WebP.

Are you sure another plugin has converted all the images? Perhaps she missed those that she cannot read, but did not let you know by mistake?
