Same problem. Updated the plugin to the latest, update failed and all existing galleries gone. Plugin no longer appears in list and reinstall fails:
Downloading install package from http://downloads.wordpress.org/plugin/nextgen-gallery.zip…
Unpacking the package…
Installing the plugin…
Destination folder already exists. C:/wordpress/wp-content/plugins/nextgen-gallery/
Plugin install failed.
Gallery 1.9.12
Wordpress 3.5.1
Like JEBERLECO I’d rather not have to recreate all the galleries 🙂
Site is a self hosted intranet, not publicly accessible
Same here. After Update nearly all Nextgen-Plugin-Files have 0-byte size.
Solved with overwriting (FTP) with V 1.9.10
@jeberleco, @robcro6010, @fezak, Make sure you all are running v1.9.12 of the plugin, and then deactivate & then reactivate the plugin. That should refresh the database tables and your images + meta should reappear.
Maybe something went wrong when (automatically) updating.
Manual upload did it.
Another automatic update to v1.9.12 was fine.
So I think the problem was/is NOT the NGG-plugin!
Quite possibly because a file or two is missing. Has nothing to do with uploading-deactivating and all that other nonsense.
I’ve an error calling for upgrade.php
wp-content/plugins/nextgen-gallery/admin/upgrade.php) [function.include-once]: failed to open stream: No such file or directory in /…/…/public_html/wp-content/plugins/nextgen-gallery/admin/settings.php on line 201
Well that upgrade.php file is not in the zip. I checked by manually re-downloading and it’s not in there, but it IS in the previous version.
Hi @freedom Builders , the upgrade.php file was removed as of v1.9.10 in preparation for v2.0 and is no longer needed. It is still mentioned in one file, causing the error that you saw, to show in some rare cases, which we are including a fix for in our next upgrade. Until we release the next upgrade, you can resolve this issue 1 of 2 ways:
a) add "error_reporting(0);" to wp-config.php
or
b) in settings/admin.php, remove line #201: include_once (dirname (__FILE__) . '/upgrade.php');
That should do the trick! 🙂
