Can you check your server logs to see if there are any PHP errors? That will help us debug. Thanks
I’ll see what I can do. Apparently 1and1 doesn’t provide access to Apache error logs on shared hosting, and I’m unsure about how to create my own error logs. If I figure it out, I’ll reply. Thanks.
I’m experiencing the same kind of problems… Can’t access to the /wp-amin URL but I need to log to /wp-admin/plugins.php for example to see my backoffice.
Also, now the website is really really really slow… as long as the facebook plugin is activated. If I deactivate this plugin, all is ok.
