Have the same issue for a week ago… But i am using free version so that I just turn it off…

@trongkhanh does your site also use Elementor?

-IJ

@deliciousbrains Yes. It cause by Elementor? I saw Elementor has a big update. But the topic owner just use Elementor Old vesion.

Hi there,
I do use Elementor, disabling Elementor Pro fixed the fatal error although I still get the same error or warnings other pages. I rolled both Elementor and Elementor pro back to older versions (3 versions back) but get the same issue. Is this specifically a conflict with Elementor?

Thanks

Thanks for the updates.

We’ve seen a couple of customers have similar issues when using the most recent versions of Elementor.

Please contact Elementor for support as it seems like a recent update started injecting strings as the width and/or height of what we presume are dynamically generated image sizes. Width and height should be integers, for obvious reasons.

Please also be aware that WP Offload Media Lite does not have the support for Elementor that WP Offload Media does.

Thanks, I have taken it up with Elementor.

@southafricanrob Have the problem solved yet? What news from Elementor?

@trongkhanh Not yet unfortunately – Elementor said they can’t provide support for other plugins, I did tell them it appeared to be an issue with them though! If it helps – in the interim I have set up my uploads folder to mount as an EFS drive which is achieving the same result of offloading the media uploads, albeit without the CDN option.

It looks like Elementor fixed the issue in v3.7.0 by disallowing strings in the width/height when using a “Custom” size for the Image widget.

We’ll have some protection in the next major release of WP Offload Media against this kind of invalid data in image sizes.

In the meantime, please update to Elementor 3.7.0 or later and then update any Images set with a custom size to make sure integer width and height are set by “Applying” the change and “Updating” the post from the Elementor editor.

In order to access the posts with invalid values in the custom sized Image widgets, you may need to temporarily deactivate WP Offload Media to avoid the invalid data issue until the data is fixed.

Please note this problem only occurs with PHP 8.0+.

Thanks for this info. I had rolled back to 3.6.5 but still had same issues, I didn’t realise the image sizes would still actually be saved incorrectly but makes sense. Thanks again for the follow up.

@southafricanrob Hi,
Don’t know why plugin developer always blame others… Maybe this is error caused by elementor but it just happen when amazon s3 and cloudfront activated. If without amazon s3 and cloudfont, elementor still working good without any string * string fatal error.

Just fix it by yourself @southafricanrob :
/plugins/amazon-s3-and-cloudfront/classes/integrations/media-library.php
Line 1203: add (int) like that
return ( (int)$a['width'] * (int)$a['height'] ) - ( (int)$b['width'] * (int)$b['height'] );

@southafricanrob please checkout WP Offload Media Lite v3.0.0, should be fixed.
