Does anybody have a solution?
I have tested Ecwid plugin for WordPress from here: https://wordpress.org/extend/plugins...
with a just upgraded version of WordPress (3.3.1 to 3.3.2), it works fine, no issues. So I basically couldn't reproduce the problem.
Can you please try deactivate and then activate your plugin in WP Admin → Plugins ? If that doesn't help, can you please removing and installing plugin again?
