Since today a lot of timeout, slow response and none (to most) pages do no longer display the tags for that page at the bottom of page.
Also the tag-cloud page does not show any tags (http://brucebase.wikidot.com/system:page-tags)
Also the tags per page does not show any tags (http://brucebase.wikidot.com/manage:pages-and-tags)
Selecting the option to add tags, the field shows no existing tags. However the pages that depend on listing these pages work and somehow can read the tags.
Example: http://brucebase.wikidot.com/song:balboa-park
This page has a tab "Performances" that list all the concert dates this song was played. As one can see the pages are listed. Selecting any of these pages, none of them display the attached tags at the bottom of the page.
If you add the tags to page (new or existing) results in displaying the tags as expected.
I have re-added the tags to this page: http://brucebase.wikidot.com/interview:2021-06-09-siriusxm-studio-new-york-city-ny
At that page now shows the tags at the bottom of the page.
