Title: [Plugin: Regenerate Thumbnails] Error while generating thumbnails for some files Last modified: August 20, 2016 --- # [Plugin: Regenerate Thumbnails] Error while generating thumbnails for some files * [mehulved](https://wordpress.org/support/users/mehulved/) * (@mehulved) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/) * I see following error while generating thumbnails for some images function (){ if(!d){var c=arguments,g,h,i,j,k;b&&(k=b,b=0);for(g=0,h=c.length;g It gives no idea as to what the problem is. And these re-sized images show up as corrupted even though the original one is fine. * [http://wordpress.org/extend/plugins/regenerate-thumbnails/](http://wordpress.org/extend/plugins/regenerate-thumbnails/) Viewing 11 replies - 1 through 11 (of 11 total) * [Jen Baumann](https://wordpress.org/support/users/dreamwhisper/) * (@dreamwhisper) * [14 years, 7 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346126) * I’m seeing this on any unattached images. * [cwulff](https://wordpress.org/support/users/cwulff/) * (@cwulff) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346144) * Same thing here. Mine’s happening regardless of whether it’s attached or unattached. I can’t find any logic to it. 69 regenerated, 66 not. I attached some of them to see if it changed, but it didn’t. * Plugin Contributor [viper007bond](https://wordpress.org/support/users/viper007bond/) * (@viper007bond) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346145) * Similar topic here: [http://wordpress.org/support/topic/plugin-regenerate-thumbnails-resize-failure](http://wordpress.org/support/topic/plugin-regenerate-thumbnails-resize-failure) * I’ll investigate. * [rjksn](https://wordpress.org/support/users/rjksn/) * (@rjksn) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346148) * Was this ever solved?

The images had to be executable( +x) by the webserver user. * [Gustavo Straube](https://wordpress.org/support/users/gutostraube/) * (@gutostraube) * [14 years, 5 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346155) * I modified images permission via FTP to make them executable and the error remains. * [Eric McNiece](https://wordpress.org/support/users/emcniece/) * (@emcniece) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346159) * Getting this too. New install on a different server.. client wanted it on their own box, but there’s so many problems… * NextGen gallery is having a ton of trouble too, with image uploading and resize. I also can’t use Advanced Custom Fields to attach images to posts. This server uses the mysqli extension instead of the usual mysql, but I suspect that there’s PHP modules missing from the installation. * [cwulff](https://wordpress.org/support/users/cwulff/) * (@cwulff) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346160) * I got it fixed not as a ‘permissions’ issue, but as an ‘owner’ issue in Apache. * The files and folders had been reset to apache as owner and I needed to change them back to my user in the file manager. * [Eric McNiece](https://wordpress.org/support/users/emcniece/) * (@emcniece) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346161) * NICE, that could totally be it. Damn shame that I don’t have shell to the server though. * [beneberle](https://wordpress.org/support/users/beneberle/) * (@beneberle) * [14 years ago](https://wordpress.org/support/topic/plugin-regenerate-thumbnails-error-while-generating-thumbnails-for-some-files/#post-2346179) * Yep, it was permissions for me. Check your _uploads_ directory and image files. The file owner should be you, group should be apache, www, or your webserver default, Permissions should be rwxrwxr-x or 664 * No shell? Contact support or find a host that offers it.
