Hi, I'm trying to add the portable infoboxes extension and I'm running into a serious issue. After just installing it, I'm unable to save any pages. I haven't used it at all, it's just installed. When I try to save articles I get the error "[YN070QVyY3ZKdDp2dlrAdgAAAU8] Caught exception of type Error." If I remove the extension the error goes away. The error occurs under both visual editor and source editor.
Also, documentation I found suggested that there should be an "infoboxes" option under the insert menu of the visual editor but I'm not seeing that.
Can anyone point me in the direction of how to get this working? Thanks!
