I finally found out what is blocking my plugin WP UI, unfortunately the error is caused by the plugin login-radius!
loginradius when the plugin is activated, the UI code table does not work properly with jquery and therefore does not make any graphic effect.
the problem is always active when loginradius is on, and I have no idea what it creates.
Please, support a lot of your plugin, but I can not use it if I get this error.
I hope you solve as soon as possible, thank you.
