Simply find this from your plugin:

expose_function('some', 'parameters', ...);

and replace it with this:

elgg_ws_expose_function('some', 'parameters', ...);

This has been documented in the plugin upgrade instructions: http://learn.elgg.org/en/1.9/guides/upgrading.html#web-services

Thanks Juho,

I found the function now thank!

They were in file_viewer plugin for elgg 1.8

I didn't realize that file_viewer was available for elgg 1.9

I've been using File Viewer 1.2.0 by Ismayil Khayredinov. It works fine now that I've changed the expose function to the new method as above.

what files is it in?

gmwestrup if you want to use the File Viewer 1.2.0 by Ismayil Khayredinov you will get the following message in admin area.

The web services are now a plugin in Elgg 1.9. You must enable this plugin and update your web services to use elgg_ws_expose_function().

Do the following to fix.

open File Viewer 1.2.0 /start.php

search

expose_function(

replace with

elgg_ws_expose_function(

Hi clu55ter,

Can you tell me if you're using web services 1.8 or 1.9 with you're Elgg 1.9 site? I'm trying to use web services 1.8 with my site because it offers more features(i.e. turning certain services on and off). The only problem is that when I update the plugin to use elgg_ws_expose_function the entire website disappears. So just curious as to if you're using 1.8 or 1.9
