I use Adminer and when i upgraded WP to 3.8 this error message showed on the page:
blockUI requires jquery v1.2.3 or later you are using v1.10.2 Image of error
After researsching in this forum they say you have to upgrade all plugins so I did that and same error was showing up.
Then they said i have to deactivate all plugins to see which plugin that gives the blockUI-error.
Then I deactivated Adminer (stupid idea) and updateted my site.
I will update the plugin to a new version.
But the error of the jquery hint and the strange menu in the frontend is not from Adminer plugin. The plugin works only inside the back end. I check this and return, if you are on front end.
