whats-new-nextgen-gallery-plus-proWe came across a bug in two versions of PHP, the coding structure behind WordPress and many other platforms.  The bug has been patched and released in a new version of PHP, but not all hosts have updated their servers with the new version. So we had to release this update which disables NextGEN Gallery on sites running the bugged versions of PHP. Here is more on that:

NextGEN Gallery makes extensive use of PHP Magic Methods to encapsulate our various data models.

The latest releases of PHP, versions 7.1.12 and 7.0.26, include some changes how reference counting of strings is conducted in the __get() magic method that is breaking NextGEN and various WordPress sites. The problem is reproducible using standard PHP code, where both a subclass and it’s parent are using the __get() magic method, and are defined to return-by-reference.

A patch and commit has been accepted into the PHP source code repository but hasn’t yet been released or distributed.

We strongly recommend rolling back to an earlier version of PHP to resolve these issues created by this PHP bug. Please contact your web hosting service provider for assistance with this process.

Backup Before Upgrading

Please consider backing up your site (both server files & MySQL Database) whenever updating plugins.  Here are some backup recommendations.


Download NextGEN Gallery from our WordPress gallery plugin page on WordPress.org or visit the Plugin page in your WordPress admin area to utilize the auto-update feature.

  1. I have read all the forums regarding the PHP 7+ bugs that may cause issues with NextGen gallery. Concerned that moving to PHP 5.6.32 might cause other new problems. In the forums, you seem to be saying you will come up with a NextGen version that does not require waiting for my host (SiteGround) to make the fixed PHP version available. What is your current time estimate for that new NextGen version to become available?

  2. As of 12/4 (3 days ago), the PHP segmentation fault bug report says that this is FIXED in the two affected versions… yet NextGEN has not been updated to stop deactivating if running either of those versions – what is status?

    1. Deactivating NextGEN Gallery was the only appropriate thing to do with such short amount of time, so sites wouldn’t crash. Since then we’ve released a patch currently being tested by the community. Here is a link.
