Forum:How can I fix/replace a distorted wordmark?

Hi everyone. Several hours ago I uploaded a wordmark onto my wiki and it worked properly. However, a couple of minutes later, when I replaced it with a different wordmark, the new one didn't show up at all. Instead I only saw a distorted version of the first one. I tried uploading several more wordmarks of standard size (250 x 65) and even deleting the first wordmark to test but it is still displayed. Can someone please tell me why this is happening to my wiki? Is there any delay between uploading and the upload taking effect? I doubt that though, since it's been 6 or 7 hours already, and whenever I upload the 1st wordmark, it works again!

Here's the link to the wordmark (I deleted all the test uploads and leave only the one I want to see):
