I uploaded the latest copy of the Commenting plugin today and I got the following error:
PHP Fatal error: Class 'Omeka_Plugin_Abstract' not found in /home/..../public_html/omeka/plugins/Commenting/CommentingPlugin.php on line 5
This error causes the entire Omeka system to crash unless I delete the entire Commenting plugin folder from the server.
Is this a relic of Omeka prior to 2.0.0 or is something wrong with my installation?
We haven't released the Commenting plugin for 2.0 + yet. The version available in the Add-Ons Directory is good through version 1.5+.
We have tagged plugins that are 2.0 compatible, http://omeka.org/blog/plugin_categories/2-0-compatible/, to make it a little easier to sort through.
Also, we have documentation for 2.0 plugins here: http://omeka.org/codex/Plugins2.0
I'm sorry, I thought I read somewhere that it was ready for Omeka 2.0! No worries then.
