This message is also showing up in my debug log. Please advise on how to correct it.

I have the same problem on my website. The expanded text of the error indicates that it’s a problem with the Facebook pixel code:

“error: you are sending a non-standard event ‘viewcategory’. the preferred way to send these events is using trackcustom. see ‘https://developers.facebook.com/docs/ads-for-websites/pixel-events/#events’ for more information.”

I have not done anything special with the Facebook pixel. If I remember correctly, I simply grabbed their canned block of code and added it to my website without any modifications. I’d love to know how to fix this!

Predrag, thanks for your help! I’m sorry that I couldn’t reproduce the problem in order to provide more information, but I very much appreciate you following up on it so promptly.

When I realized that my “unsmushable” files were all named with something like “150×150.png” at the end, I thought that perhaps the problem was with the thumbnails behind the scenes. I used the Regenerate Thumbnails plugin to regenerate all of my thumbnails and then WP Smush seemed to work just fine. All of my files are now successfully smushed.

Because I cannot recreate the error at this time, I unfortunately cannot provide a screenshot for you. Here is the order in which I did the things that seemed to produce the error originally, so perhaps you can recreate it on your side …

1. Uploaded media files.
2. Installed the Media File Renamer and Regenerate Thumbnails plugins.
3. Renamed some files but forgot to regenerate their thumbnails.
4. Installed the WP Smush plugin.
5. Tried to smush all media files — errors!

Please let me know if this helps. If you are unable to recreate the problem, maybe I can try again.
