I upgraded the plugin and on trying to re-activate it the site hung and nothing happened. I refreshed and tried again, but still no result.
I found two errors in the apache logs and wondered if someone might be able to determin how I can get the plugin re-activated:
The first was this:
WordPress database error Duplicate key name 'meta_id' for query ALTER TABLE wp_wassup_meta ADD UNIQUE KEY meta_id (
meta_id) made by activate_plugin, do_action('activate_wassup/wassup.php'), call_user_func_array, wassup_install, wassup_tableInstaller, wUpdateTable, wCreateTable, dbDelta, referer: .../wp-admin/plugins.php
So I dropped the table as it was empty and then got this error when I tried again to activate the plugin:
PHP Warning: mysql_free_result() expects parameter 1 to be resource, boolean given in .../wp-content/plugins/wassup/lib/upgrade.php on line 290, referer: .../wp-admin/plugins.php?activate=true&plugin_status=all&paged=1&s=
Then of course the previous table has been re-added so on trying to activate the plugin apache reverts to the previous error.
