Plugin cannot be deactivated

Hi @chivkea,

Thanks for using NextGEN Gallery Optimizer, and apologies for any inconvenience.

The blank page you’re experiencing is due to a fatal error caused by the major NextGEN Gallery v2.0.7x update, released recently on the 19th of February 2015. Unfortunately, as I’ve detailed on Optimizer’s main plugin page, Optimizer is not currently fully compatible with this release.

As key parts of the NextGEN v2.0 API were completely removed in this update (without any graceful deprecation, or backwards-compatibility in place), Optimizer (and likely many other NextGEN extensions) will display fatal errors, and not function correctly with this release, until all affected integration components are rewritten.

The reason the plugin won’t deactivate properly, is due to the presence of a fatal error (only visible when WP_DEBUG is active), which is caused by the complete removal of the C_Lightbox_Installer class (and its uninstall_lightbox() method) in NextGEN Gallery v2.0.7x.

I’ve been hard at work on the next update for Optimizer (including full support for NextGEN v2.0.7x), and I should have it ready for release in the next few days, after thorough testing. In the meantime, however, and to ensure a smooth update process, I would recommend rolling-back to the immediately-preceding, fully-compatible, stable release of NextGEN v2.0.66.37.

Optimizer’s broad, existing compatibility with NextGEN (v2.0.0 to v2.0.66.37), NextGEN Legacy (v1.6.2 to v1.9.13) and NextCellent Gallery remains unaffected.

I hope this helps, and thank you for your patience.

Cheers,
Mark.

Hi @bmhiexeter,

Just so other readers are clear, the unnamed plugin you have purchased a license for is NOT Optimizer Pro.

And, for some context, you are using a free version of a GPL-licensed product (i.e. PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND), yet are requesting (if not demanding) either free support, or financial compensation for incompatibility with some other author’s premium product. Not cool.

With that said, I would be happy to help you out, but have you read the immediately preceding post in this support topic (or the full-screen notice at the top of Optimizer’s main plugin page), at all? It fully details everything you need to know regarding this issue, including the actual cause, and how to fix it.

I’ll post it again for you (so you get it via email), and I’ll include some extra links you might find helpful in rolling-back.

Do let me know if you have any questions or further issues, and many apologies in advance for any inconvenience caused.
