Incompatibility with Meta Slider

Yup, it turned out that’s what it was, and if you leave the original image on the server the problem goes away.

Seems like this is something you might want to look into.

Thanks for the feedback. Leaving the ‘Remove Files From Server’ option disabled will ensure better compatibility with other plugins.

We’ve had a couple of requests for support with Meta Slider, so it’s something we’re looking into.

Cheers,

@a5hleyrich ~ I would be happy if you can resolve this problem, of course, but would it be possible in the meantime to give us some way of bypassing the all or nothing solution? I’m thinking of maybe some text or maybe a class we could use to create a local link for (meta slider) images, for example.

The problem is with meta slider not offload S3, meta slider isn’t setup to work with amazon S3 URLs. The solution is to add this to your function.php file.

//Allow meta slider to get images from amazon S3
/**
 * Use wp_get_attachment_url to retrieve the attachment URL
 *
 * Important: Resized images created by Meta Slider are not uploaded to s3.
 * Important: Disable cropping in the slideshow settings to stop Meta Slider from outputting a URL to a file that doesn't exist on S3.
 */
add_filter('metaslider_attachment_url', 'metaslider_s3_cloudfront_url', 10, 2);
function metaslider_s3_cloudfront_url($local_url, $attachment_id) {
	return wp_get_attachment_url($attachment_id);
}

That doesn’t seem to be working. The image is still corrupting.

That’s odd. Are you using a caching plugin? if so, try clearing out the cache.

No, no caching plugin.

The site is on CloudFlare reverse proxy.

Could this be another one of those Chrome things I wonder?

I can now see that if I upload the image to the server with “leave original on the server” activated, there is no problem and it works as expected. However, if “delete original from the server” is activated, when the image is uploaded, it is not possible to use it in Meta Slider and produces the result I showed earlier.

The fix involves deleting the images which were uploaded when “delete original” was activated, deactivating it, and then re-uploading the images. They then work with Meta Slider.

No idea what’s happening or why.

I thank @davehealey for his contribution but it didn’t seem to make any difference.
