Title: Fatal PHP error Unsupported operand types: string * string Last modified: August 11, 2022 --- # Fatal PHP error Unsupported operand types: string * string * Resolved [southafricanrob](https://wordpress.org/support/users/southafricanrob/) * (@southafricanrob) * [3 years, 10 months ago](https://wordpress.org/support/topic/fatal-php-error-unsupported-operand-types-string-string/) * Hi there, Thanks for an excellent and really easy to use plugin. I have been using it with now problems for a while but have suddenly run into an issue where if I enable “Rewrite Media URLs” (I am using Cloudfront) then I get a fatal PHP error on the frontend. Debugging give me this error: * ``` Fatal error: Uncaught Error: Unsupported operand types: string * string in /var/app/current/wp-content/plugins/amazon-s3-and-cloudfront/classes/integrations/media-library.php on line 1203 ``` * This seems to indicate that wp_get_attachment_metadata isn’t returning valid dimensions? The wp_get_attachment_metadata value in the database contains this array which seems to contain the correct dimensions. * `a:6:{s:5:"width";i:566;s:6:"height";i:450;s:4:"file";s:36:"2022/08/62cc37c908f43219140781- 6.jpg";s:8:"filesize";i:18577;s:5:"sizes";a:2:{s:6:"medium";a:5:{s:4:"file";s: 36:"62cc37c908f43219140781-6-400x318.jpg";s:5:"width";i:400;s:6:"height";i:318; s:9:"mime-type";s:10:"image/jpeg";s:8:"filesize";i:21092;}s:9:"thumbnail";a:5:{ s:4:"file";s:36:"62cc37c908f43219140781-6-150x150.jpg";s:5:"width";i:150;s:6:" height";i:150;s:9:"mime-type";s:10:"image/jpeg";s:8:"filesize";i:7102;}}s:10:" image_meta";a:12:{s:8:"aperture";s:1:"0";s:6:"credit";s:0:"";s:6:"camera";s:0:""; s:7:"caption";s:0:"";s:17:"created_timestamp";s:1:"0";s:9:"copyright";s:0:""; s:12:"focal_length";s:1:"0";s:3:"iso";s:1:"0";s:13:"shutter_speed";s:1:"0";s: 5:"title";s:0:"";s:11:"orientation";s:1:"0";s:8:"keywords";a:0:{}}}` * I have disabled all plugins and set a default theme but am getting a consistent error. Any suggestions would be most welcome.

I rolled both Elementor and Elementor pro back to older versions (3 versions back) but get the same issue.

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. * [https://deliciousbrains.com/wp-offload-media/doc/elementor-integration/](https://deliciousbrains.com/wp-offload-media/doc/elementor-integration/) * -IJ * Thread Starter [southafricanrob](https://wordpress.org/support/users/southafricanrob/) * (@southafricanrob) * [3 years, 10 months ago](https://wordpress.org/support/topic/fatal-php-error-unsupported-operand-types-string-string/#post-15919066) * Thanks, I have taken it up with Elementor. * [SeCrEt BoY™](https://wordpress.org/support/users/trongkhanh/) * (@trongkhanh) * [3 years, 10 months ago](https://wordpress.org/support/topic/fatal-php-error-unsupported-operand-types-string-string/#post-15922884) * [@southafricanrob](https://wordpress.org/support/users/southafricanrob/) Have the problem solved yet?

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. * Plugin Author [Delicious Brains](https://wordpress.org/support/users/deliciousbrains/) * (@deliciousbrains) * [3 years, 10 months ago](https://wordpress.org/support/topic/fatal-php-error-unsupported-operand-types-string-string/#post-15927437) * 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+. * -IJ * Thread Starter [southafricanrob](https://wordpress.org/support/users/southafricanrob/) * (@southafricanrob) * [3 years, 10 months ago](https://wordpress.org/support/topic/fatal-php-error-unsupported-operand-types-string-string/#post-15928690) * Thanks for this info.
