And the next error. Changing lightbox effect causes this one:

Warning: preg_match() [function.preg-match]: Compilation failed: unrecognized character after (?< at offset 21 in /home/www/web97/html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/router/mixin.url_manipulation.php on line 154

Your memorylimit ist too low (only 64M). Access your wp-content/plugins folder via FTP and replace NGG with an older version (1.9.13). This version you can download here, if you have not made a backup: Download Nextgen Gallery 1.9.13

However, your memorylimit is very low for today. You should contact your hoster for a higher limit (e.g. 128M).

It works for me! Just installed the hotfix and the error is gone. Thank you very much! No i ′m waiting for the stable version.

Update: changing the lightbox effects to anything other then “Fancybox” causes a new error:

Warning: preg_match() [function.preg-match]: Compilation failed: unrecognized character after (?< at offset 4 in /home/www/web97/html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/router/mixin.url_manipulation.php on line 154

Same problem here. All other plugins deactivated and the error was still there.

Downgrading works, but that′s no solution.

It′s definitly the best not to upgrade: “8 people say it works.
26 people say it’s broken.”

V2 has several bugs. If you give it a try, rember this rollback guide: How to rollback a version

Your memorylimit ist too low (only 64M). But you can manually downgrade to V 1.9.13: How to rollback a version

But you still need a higher memorylimit. 64M is really low today. You should contact your hoster for a higher limit.

Exactly the same error here. Disabled all other plugins: no effect, the error is still there. Switched Permalink to standard: no effect. PHP-Version is 5.3.8

Thank you so much! The new version works just perfect. I have also tested in with WordPress 3.6alpha and it works too.

No, you need to do this modification only one time, until the next update of NextGen Gallery.

First you open your FTP-Tool (e.g. Filezilla) and navigate to yourdomain//wp-content/plugins/nextgen-gallery. Find the file ngg-config.php and download it to your computer. Open this file with your editor (e.g. Notepad++) and find

require_once( WP_LOAD_PATH . 'wp-load.php');

It should be the last line in this file. Replace this line with

require_once( WP_LOAD_PATH . 'wp-admin/admin.php');

Save the file and upload it, replacing the old version. That′s it, you′re done.

It′s a bug in NextGen. You have to edit ngg-config.php.

Find:

require_once( WP_LOAD_PATH . 'wp-load.php');

Replace with:

require_once( WP_LOAD_PATH . 'wp-admin/admin.php');

Save and upload the file. I hope this will be fixed in the next version of NGG

Same here. After the update to WordPress 3.3, the CKEditor is lost. Tried the dev version and it works for me.
