Apologies for the issues with the recent update. There has been reports of Tabs/accordions working erratically - Please try the following.
Options page -> Posts tab -> Title Template and clear the field and save the options.
2) Clear the cache(!!!! hit Ctrl+F5 for a second ) and re-check tabs.
Admin page tabs
If admin page tabs have gone missing - You might have missing files. In such case You might need to reinstall the plugin. Console errors on Firebug might confirm this. ( regarding init.js missing).
Choosing old version script
Other widget issues might be solved by choosing "Options page -> Advanced -> Use old scripts instead of rewritten ones".
Thanks for the patience.
