I have my site carlosibanezlab.se running for a few years. Great! I have now made a second wordpress installation in a subdirectory to support a second site. Everything alright except that the admin bar now shows only in the second installation but no longer in the first. It flashes briefly (in both the site itself and its admin page) but then disappears. But it shows correctly in the second site running from the second wordpresss installation in the subfolder. My theme is Atahualpa latest version in both cases.
Why is this? Has this been seen before? How can I get it working again?
Thanks for help?
