Home Forums Back End WP: Can’t attach Featured Image Re: WP: Can’t attach Featured Image


I’m in trouble with this error too. Until now I discover that ngggallery last version add some options in wp-settings-{userid} cookie. After remove ngg the cookie remains (several entries in WP database refers to ngg after remove). In Chrome developer tools if you delete the cookie
(Resources->Cookies->{yourdomain}) you can set and remove post thumbnail again. I have several plugins and this can cause a “plugin hell”. But in my tests I installed a new version just with WP (post thumbnail ok) after install last version of ngggallery no more post thumbnail. After remove ngggallery the problem remains. No other plugins in my test site. I’m trying remove the creation of things like ‘imgsize=thumbnail&align=none&ngg_show_update_notice196=1&ngg_upload_resize=1‘ that remains after ngggallery install. See your {prefix}_postmeta table and search for records with ‘ngg’. If you have new information about this problem, please share the news.
