   Hey, when I upgraded to 2.7 today I also upgraded my NextGen Gallery plugin. Everything works fine except I get this error whenever I try to save a post that I'm working on:

   Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'searchnggallerytags' was given in /public_html/wp-includes/plugin.php on line 166

   Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'searchnggallerytags' was given in /public_html/wp-includes/plugin.php on line 166

   Warning: Cannot modify header information - headers already sent by (output started at /public_html/wp-includes/plugin.php:166) in /public_html/wp-includes/pluggable.php on line 850

   Right now I have to deactivate the plugin to save anything! My theme only calls the nextgen gallery header for those pages that are in my "gallery" category, fyi.
   Please help!

   Please delete the plugin folder and reload all files again

   Same problem with the same error messages, even after upgrading to 1.01. Any other ideas?

   btw I know things are probably crazy right now, thanks for taking the time to quickly get back to me.

   The filter "searchnggallerytags" is not longer a part of NextGEN-Gallery. I feel you have not proper updated all files or some other older with old files. Please recheck via FTP if you have only on plugin folder (nextgen-gallery)

   I have same problem. I have deactivated and removed directory from plugin directory and downloaded latest version (1.0.1) and installed and activated.

   Am I missing something?

   normally not, deactivate all other plugins for a test

   Hey! I believe I may have a clue. I deactivated every plugin except NextGen, and then one by one reactivated them. The plugin that caused the error seems to be Search Unleashed, if I deactivate it it works fine! I'm sure you don't know how to fix it since it's their plugin, but maybe this helps.

   Ahhh, that's the problem. Try to reset Search Unleashed to default settings, I belive it still remind the old filter settings...

    Well, I have that plug in as well, so maybe you are on to something there. Odd that it would complain about one plugin, but really be another plugin that caused the problem. I will test it out.

    So, why would Search Unleashed have a problem when NextGen was active? If I deactivate NextGen, I can reindex, etc. with Search Unleashed. However, if I active NextGen, Search Unleashed errors when I try to reindex posts.

    Because Search Unleashed recognize that Nextgen added some filter hook (v0.99) and added the gallery to the post afterwards. Now you update NextGEN Gallery and I have changed the filter name, so Search Unleashed needs to be reset or reinit now...

    Ok. So, how do you reset or reinit Search Unleashed?

    BTW, thanks for the quick responses on the questions!

    Please ask the author of this plugin, I've currently no time to analyse this deeper, as my plugin still needs some rework.

    Hey, I've uninstalled and then reinstalled the Search Unleashed plugin, and there is still an error. Looks like something we'll have to take up with Search Unleashed.

    I'll tag this as "Search Unleashed" and hopefully their developer will take a look. Thanks a lot Alex! The plugin is great!

    in search-unleashed/modules/nextgen_gallery.php lies the reference to the nextgen searchnggallerytags hook.

    // Action calls for all functions
    add_filter ('the_content', 'searchnggallerytags');
    add_filter ('the_excerpt', 'searchnggallerytags');

    simple workaround until the author fixes the plugin dependencies is to comment the lines.

    // Action calls for all functions
    //add_filter ('the_content', 'searchnggallerytags');
    //add_filter ('the_excerpt', 'searchnggallerytags');

    Having this problem still, the fix provided by kimpenhaus worked though. Hopefully the developer figures this one out!

    The developer of the Search Unleashed plugin asks for help:

    Today I updated to Nextgen 1.2.1 and Search unleashed 0.2.7 and I got the following error, even if nextgen is disabled:

    Fatal error: Class 'search_nextgen' not found in /is/htdocs/.../wp-content/plugins/search-unleashed/models/spider.php on line 17

    The error is on the admin page as well as on the search results page.

    @dhoffmann

    You need to edit /wp-content/plugins/search-unleashed/modules/nextgen-gallery.php, and remove the "/*" and "/*" chars, and then uncomment the two lines mentioned in the post before by kimpenhaus.

    smamulski is right, that's what just worked for me!

    I did the changes in search-unleashed/modules/nextgen_gallery.php and I tried the thing with /* and deactivated nextgen-gallery, but unfortunately it is not working.

    Is there still someone working on it?

    Thanks a lot,

    Yeah, I just found that on my site, and freaked, thinking I'd been hacked.

    I rolled back to the last version of Search Unleashed, which fixed the problem, at least for now... my site was down for about 24 hours before I noticed.

    Hope this gets fixed in the next release...
