I'm using a plugin to manage an avatar in a sidebar widget. On the page if I upload an image, I have to navigate away from the page, then back to it to delete it. Otherwise, it takes two attempts to remove it. Same thing with uploading the image. If I delete an image, I can't just simply upload another image in its place unless I do it a second time, then it works. If I navigate away from the page, then back again, it works fine on the first try.
Is this a caching issue or what? Permissions on root dir is set to 775
