This also happened to me once I updated to the latest version of wordpress..

I have this issue with The filename length value also, no matter what I change the number to the error keeps coming back.

I have this issue also.

Yes I still get the same errors with that theme.

I have several plugins installed, what plugin do you think may be clashing? I am using the latest version.

What I think may be causing the issues, is filosofo-custom-image-sizes. This is built into my sites theme and i’ve had a few errors with it in the past. I may be wrong, but have you had issues with this in the past?

I also get this error when trying to save media settings. When I disable Smush.it, it solves the issue.
