Hello,
I see similar but not quite exact problems to this. Here are the details:
In the WordPress admin panel, Settings, UpdraftPlus Backups, I am taken to the usual UpDraftPlus Backup/Restore page. Clicking on the tabs for Existing Backups, Settings, Debugging do not display the appropriate content and leave me stuck at the Current Status page. Backup Now produces no result. Restore switches tabs to the Existing Backups tab but I am unable to switch to any other tab from there.
Same exact result on OS X Yosemite, Windows 8 using Safari, Chrome, IE, FireFox.
All other plugins have been disabled. Memory limit increased.
My Web Inspector shows an error:
undefined is not a function (evaluating 'jQuery("#updraft-poplog").dialog("isOpen")')
Thoughts?
Thanks in advance.
Chris
