Upgraded to 2.2 this morning, and have found that I can not have more than 1 PHP widget running at a time. If I have a second one placed in either sidebar, I get a duplication of whatever PHP widget was installed first. i.e., the Daily Top 10 Posts. There are two lines of PHP for this plugin - one to show top posts overall, one to show the daily top 10. Putting one line into PHP Widget 1 and the other into PHP Widget 2 outputs the value of PHP Widget 1 in both places. Checked and rechecked to make sure I didn't duplicate the code in the two widgets.
Also happens with other PHP widgets as well (like the Technorati plugin).
I know of one other user who had seen this (johnchow.com) and the fix was to downgrade back to 2.1.3.
Has anyone else experienced this or have a suggestion for a remedy? Thanks very much.
