The last days I noticed some weird behavior in one of my WP installations. I use the Extended Categories widget because when using the dropdown for categories it also displays child-categories. Last week I noticed that the dropdown doesn't work. When I choose a category, the default permalink is used (not the pretty one that I use) and the url changes, but the index appears. When I turn the dropdown in a list, the widget uses the correct permalink and everything works. When I change back to dropdown, the correct permalink is used and everything works, but then when I check again later, the incorrect permalink (that is to say, even with the default permalink it should work, right?) is used again and the problem reappears. Of course I only think to check when at work, so I can only try IE6. I have no idea where to look for the problem. The same thing occurs with the default category widget using dropdowns and this is the only installation in which this occurs (the only one in which I have the Extended Widget Plugin installed too). The only thing I can think off is some conflict between the widget and WP Super Cache (permalinks change when a cached page expires or something, but clear WP cache makes no difference, everything keeps working just fine. I just don't know anything else that could cause the permalinks to change after a while).
Ideas anyone?
(I've just been meddling with it, so everything seems to work just fine at the moment, perhaps somebody can try with another browser.)
