No idea, why this version hasn\u00c2\u00b4t been as rigorously tested as earlier versions. There are numerous changes to the main tables that come without any warning<\/a> – numerous incompatibilities even with disabled plugins and the first time that I am really in trouble with WordPress. Fortunately I was working with backups and did a pre-flight. This is what I recommend<\/p>\n

    \n
  1. go back to your last WORKING version of database and scripts<\/li>\n
  2. DISABLE all plugins<\/li>\n
  3. select the STANDARD THEME<\/li>\n
  4. maybe you need to fake the database ID in the options table?<\/li>\n
  5. delete all scripts except those in \/WP-CONTENT<\/li>\n
  6. copy the new scripts to the server<\/li>\n
  7. login in as admin and wait until the system updated your database tables<\/li>\n
  8. update also all PLUGINS and activate one by one EXCEPT UltimateTagWarrior<\/li>\n
  9. import tags from UltimateTagWarrior under Admin\/Manage\/Import<\/li>\n
  10. the current EventCalendar will disable your site search – leave it inactive for now<\/li>\n
  11. select YOUR theme<\/li>\n<\/ol>\n

    The only thing that really helps is to cut and paste any error message into a google search: You may also want to check these links 1<\/a> + 2<\/a>.
    \nSorry, if you see here occasionally popping up error messages – I am not sure if I really found all quirks.<\/p>\n
