Yep, me too,
Ive been sticking with version 2.0.4 because every update after that has just not worked for me.
Updated this plugin yesterday and was pleased to see it finally working OK.
That is - until I tried to do some things in WP-Admin today.
Really weird behavior; some of my other plugins just didn't work at all, some redirected me to the login screen and a lot of the core functionality of wordpress would not work also.
Basically, I couldn't edit anything!
The worst of it was, I thought we had been hacked again because I had accidentally left permissions on wp-content set to 0777 for several days prior to this happening.
Spent most of the day deleting files and re-creating databases before I finally twigged to the reason.
Running wp v3.4.2, php v5.3.18, MySQL v5.5.27 on an xen VPS with about 40 other plugins - which all play happily together - except this one.
Reverted back to v 2.0.4, and all is well again.
Keep up the good work Mike!
