Title: Illegal string offset errors with Thesis theme Last modified: August 21, 2016 --- # Illegal string offset errors with Thesis theme * Resolved [asmichael](https://wordpress.org/support/users/asmichael/) * (@asmichael) * [12 years, 1 month ago](https://wordpress.org/support/topic/illegal-string-offset-errors-with-thesis-theme/) * We’re running WP 3.8.3 running the Thesis them and recently updated our plugin to 7.4.4. * With that, we started receiving the following error on specific pages: [http://thethriftycouple.com/wp-content/uploads/2014/04/error-from-nextgen.jpg](http://thethriftycouple.com/wp-content/uploads/2014/04/error-from-nextgen.jpg) * Warning: Illegal string offset. ‘width’ in …media.php on line 252 Warning: Illegal string offset. ‘height’ in …media.php on line 252 * I understand from another ticket that this might be due to another plugin not implementing a call correctly to `wp_get_attachment_metadata()`: [http://wordpress.org/support/topic/warning-illegal-string-offset-6](http://wordpress.org/support/topic/warning-illegal-string-offset-6) * In the meantime, I have added a defined Image URL for that page (understood – that’s best practice anyway) but am concerned about all the other pages that might be showing this error. * I did try to go in and find the option “WP Auto-Resize” under the General tab in the settings but cannot find it. Even if I did, is this just a workaround that might have other ill effects? * Should this bug be handled differently with the different version of NGFB? I apologize but wonder if this is happening with other plugins wonder if there is a better way to handle this – possibly by checking whether the height/image is missing upon call to `wp_get_attachment_metadata()` and handling that error instead of generating the warnings back to the user? * Thank you so much for this plugin – it truly has solved many of our problems. My request it to find a fix and give you update that this is a problem with this specific configuration – assuming others might have this issue as well. * [https://wordpress.org/plugins/nextgen-facebook/](https://wordpress.org/plugins/nextgen-facebook/) Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Author [JS Morisset](https://wordpress.org/support/users/jsmoriss/) * (@jsmoriss) * [12 years, 1 month ago](https://wordpress.org/support/topic/illegal-string-offset-errors-with-thesis-theme/#post-4813819) * The error is because `wp_get_attachment_metadata()` did not return any information for the image size in question. It’s assumed the image size exists because an earlier call to `image_make_intermediate_size()` should have created it (if it didn’t exist). And that’s where the problem is – never assume. 😉 * I’ll add an extra check to control that condition and release an update shortly. * Meanwhile, make sure the “Auto-Resize Images” option (on the NGFB Advanced settings page) is checked. This should create the missing sizes. If WordPress can’t create the image size, then you might have to uncheck the “Ignore Small Images” option– at least until I can push out the next version (probably later today). * Thanks, * js. * Plugin Author [JS Morisset](https://wordpress.org/support/users/jsmoriss/) * (@jsmoriss) * [12 years, 1 month ago](https://wordpress.org/support/topic/illegal-string-offset-errors-with-thesis-theme/#post-4813826) * Correction – it’s the width / height information for the original / full-size image that’s missing from the image metadata. That’s not good. You might want to use a plugin like “Simple Image Sizes” to regenerate your image sizes and fix the WordPress image metadata. * I’ll code an appropriate error in the upcoming version. * js. * Plugin Author [JS Morisset](https://wordpress.org/support/users/jsmoriss/) * (@jsmoriss) * [12 years, 1 month ago](https://wordpress.org/support/topic/illegal-string-offset-errors-with-thesis-theme/#post-4813920) * Are you ok with installing plugins from ZIP files? If so, you can install the following new version, and it should fix your problem. 😉 * [http://downloads.wordpress.org/plugin/nextgen-facebook.7.4.5.zip](http://downloads.wordpress.org/plugin/nextgen-facebook.7.4.5.zip) * If you need help uninstalling the old version and installing this ZIP file, see here: [http://wordpress.org/plugins/nextgen-facebook/installation/](http://wordpress.org/plugins/nextgen-facebook/installation/) * js. * Thread Starter [asmichael](https://wordpress.org/support/users/asmichael/) * (@asmichael) * [12 years, 1 month ago](https://wordpress.org/support/topic/illegal-string-offset-errors-with-thesis-theme/#post-4813965) * Wow – thank you so much for all your responses and the quick resolution! I am ok to install it via zip and will get that done later today when I have access. * Thanks so much!

You should see the update in your WordPress admin interface. 😉 * js.
