I am attempting to add HTML code, in the form of a live status banner, to my Ark server advertising forum post. I click code at the top, paste in the HTML provided by arkservers.net, and click insert into text. It appears as raw code when finished, even after saving changes to the post. I tried to go around this issue by inserting the image by URL (insert other media > insert image from URL). This appeared while in editing mode, but after I saved changes to my post, it vanished. Here are the two separate lines of HTML I was trying to add: 

<a href="https://arkservers.net/server/64.94.95.218:27457" target="_blank"><img src="https://arkservers.net/banner/64.94.95.218:27457/banner.png" alt=""></a>

AND

<iframe src="https://arkservers.net/api/widget/1/64.94.95.218:27457" frameborder="0" scrolling="no" width="474" height="86"></iframe>

Is there something I'm doing wrong?

Thanks,
