PNG black background

Could you post a link to a page on your site that shows the problem you’re having?

Yes, please post a link or screenshot.

Sorry guys. I was busy. https://jamieperlman.com/contact/

As you can see the png has black background.

Looks like the file itself is corrupt at: https://jperlman.valleryarts.com/wp-content/uploads/2014/08/contactdesign1-1024×887.png

I attempted to open the file in Photoshop and am receiving an error that the file format module cannot parse the file.

Unless you’ve run a plugin or something to alter the images on your site, I’m not sure this is a WordPress issue. Have you tried replacing one of the images with a new copy to see what happens?

Yes I tried to replace with new png. I do have 2 plugins running to mark the image with watermark and prevent someone to save the image. I turned off those plugins and I still receive black background. I can try deactivate thise plugins again tonight.

I am starting to think it is WP cache but sadly none of clearing cache plugin works because button is not visible anywhere on the dashboard. I already filed bugs. Is there a way to clear WordPress cache manually?

I had the same happen on my site. The.png files were fine, .. until I tried changing the width (wrapper or body) for the site, then the background on 1 png file went black (all other pngs are unaffected) . When I switch back to default wrapper width the background for that file is transparent again! However, this is only the case in ie! (and I’m using ie 11, not 6!) in firefox the backgrounds become overlays, covering the image and are opaque (alpha appears to be about 8), regardless of site width. And finally, in chrome, they are actually transparent, also regardless of site width! so weird! anyone have any clues about this? I need my site wrapper to be more narrow than default to look right, so I’m stumped! I tried replacing the files but its the same result.
