I apologise if this is a duplicate issue, however I have searched and was unable to find anyone else with the same problem.

I'm using Drupal 7.12

I created a panel and inserted new custom content with full html.

I created a list using the ul tags.

I found that after installing CK editor, ul and br tags are now being ignored. h1 and img tags are still going through correctly. I disabled CK editor and deleted it from my server, but I still have the problem. I have tried using both filtered and full html and they both don't work. I also went into configuration/text formats and deselected limit allowed HTML tags, convert line breaks into html, and correct faulty and chopped off html.

I have also inspected the element and can see nothing that references the html being filtered at all.

Please help! This is driving me insane!
