If that is the case, this seems to be something in your configuration. * Would you mind sharing with us the information visible at Gallery > Overview > site details? * Many thanks! * – Gaby * Thread Starter [odim](https://wordpress.org/support/users/odim/) * (@odim) * [7 years, 7 months ago](https://wordpress.org/support/topic/thumbnail-error-when-editing-a-thumbnail/#post-10870325) * Hi, * Well, they are hosted with WpEngine. * As I mentioned I tested it on my localhost with a fresh install of WordPress and a fresh install of NextGen gallery. I ran into the same issue. * Here is the screenshot of the overview: [https://prnt.sc/lh8q4z](https://prnt.sc/lh8q4z) * Thanks. * Plugin Contributor [Imagely](https://wordpress.org/support/users/imagely/) * (@imagely) * [7 years, 7 months ago](https://wordpress.org/support/topic/thumbnail-error-when-editing-a-thumbnail/#post-10879878) * Hi [@odim](https://wordpress.org/support/users/odim/), * Thanks for providing the screen. The server details look fine. * Let’s check to see if there is a plugin conflict happening. Temporarily deactivate all plugins, then reactivate NextGEN Gallery only. Does the issue still appear? If so, temporarily switch to a WordPress default theme (this deactivation is only intended to quickly check to see if the issue goes away or is still present). If by deactivating the other plugins the issue does go away, reactivate each of the other plugins one at a time to locate the culprit. Keep me posted on your results 🙂 * Mihai * Thread Starter [odim](https://wordpress.org/support/users/odim/) * (@odim) * [7 years, 7 months ago](https://wordpress.org/support/topic/thumbnail-error-when-editing-a-thumbnail/#post-10880730) * Hi, * Ad I mentioned I have installed a fresh WordPress install with no plugin the only plugin running is Nextgen gallery. * Also, I am using the default twentyseventeen theme. * 1. Using twentyseventeen theme installed fresh for the sake of testing the plugin. * 2. Only activate Nextgen Gallery nothing else. * Thanks * Plugin Contributor [Imagely](https://wordpress.org/support/users/imagely/) * (@imagely) * [7 years, 7 months ago](https://wordpress.org/support/topic/thumbnail-error-when-editing-a-thumbnail/#post-10889436) * Hi [@odim](https://wordpress.org/support/users/odim/) * I noticed in one of your screenshots that you are using a PHP 5.6.36 Could you please try to adjust that to PHP version 7.2 or higher?
