Title: [Plugin: NextGEN Gallery] Upgrade loop Last modified: August 19, 2016 --- # [Plugin: NextGEN Gallery] Upgrade loop * [welshpixie](https://wordpress.org/support/users/welshpixie/) * (@welshpixie) * [16 years, 8 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/) * Recently upgraded to 1.3.6 version of NextGen. * Works fine from admin side. Activated the plugin sidewide. Now when non-admin users try to manage their gallery, they are directed to this message: * ‘Upgrade NextGEN Gallery * The script detect that you upgrade from a older version. Your database tables for NextGEN Gallery is out-of-date, and must be upgraded before you can continue. If you would like to downgrade later, please make first a complete backup of your database and the images. * The upgrade process may take a while, so please be patient. Start upgrade now…’ * I see this also when back-ending a user’s blog. Clicking ‘start upgrade now’ claims to upgrade successfully but then loops back to the error page detecting an older version. * Tried uninstalling, deleting, and reinstalling the plugin to no avail. * Any ideas?

But **all subsites can’t get out of the “upgrade loop”.** * This is a new setup/installation and I do not have any content I need to keep, at least in terms of images/galleries. * I also tried moving /wp-content/**plugins**/nextgen-gallery/ to /wp-content/** mu-plugins**/nextgen-gallery/ but then I don’t even see the plugin appear at all in the WP Admin Panel. * **Is there any trick to correctly install NextGEN Gallery for WP3 MU?** * Please advise… * [Strategerizer](https://wordpress.org/support/users/rneagu/) * (@rneagu) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229520) * Found solution from another thread: [http://mu.wordpress.org/forums/topic/15437](http://mu.wordpress.org/forums/topic/15437) * Basically log in as SuperAdmin in the Subsite showing issue, go to Plugins and Deactivate, then Network Activate again the NGG plugin. * I guess I deleted the plugins, my customizations and database tables unnecessarily trying to fix the harder way… * Good to have it working again! * [Alex Rabe](https://wordpress.org/support/users/alexrabe/) * (@alexrabe) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229521) * have you tested the latest beta ??? * [puzzledust](https://wordpress.org/support/users/puzzledust/) * (@puzzledust) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229522) * How do you log in as the SuperAdmin? I am the one and only admin for my site and still don’t get the “network activate” option. I am using the latest beta. * [Alex Rabe](https://wordpress.org/support/users/alexrabe/) * (@alexrabe) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229523) * try version 1.5.5, seems to be you have the standard WordPress installation * [shuette](https://wordpress.org/support/users/shuette/) * (@shuette) * [15 years, 9 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229526) * Thanks for all your hard work Alex! The current version of NGG 1.6.0 is working great with WP 3.0.1 in multi-site mode after a simple “Deactivate Sitewide” and re-“Network Activate”. * Love your work! * [oldboygla](https://wordpress.org/support/users/oldboygla/) * (@oldboygla) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229533) * For anyone that is still having issues with this and none of the above fix it, I think it’s caused by having a non-default table prefix on your WordPress installation. * All my tables were prefixed with **ng_** and it looped around the before-mentioned upgrade error. * You can rename your table prefix with [WP Prefix Changer v1.1 Plugin](http://blogsecurity.net/wordpress/wp-prefix-changer-v11-released) by [Blog Security.net](http://blogsecurity.net/). * or * Configure it manually by following this handy guide: [6 Simple Steps To Change Your Table Prefix In WordPress](http://tdot-blog.com/wordpress/6-simple-steps-to-change-your-table-prefix-in-wordpress). * You’ll probably have to change it to the default “**wp_**” prefix to get it to work. I haven’t tested it yet myself, but I think it might work. * [Heintraag](https://wordpress.org/support/users/heintraag/) * (@heintraag) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229534) * Thanks OldBoyGLA i think you just gave me a solution to my problem. I am missing the Import Image Folder option all of sudden and have been trying to trace where i might have changed something. * Turns out i recently changed the default wp_ prefix to something else for extra security.. maybe this also influences how nextgen imports folders? * [Heintraag](https://wordpress.org/support/users/heintraag/) * (@heintraag) * [15 years, 8 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-upgrade-loop/page/3/#post-1229535) * No good. Nextgen stil does not allow me to Import image folder even when i changed the table prefix back to wp_ * I hope Alex might find the time to shed some light on this as i do not know how to solve this.
