Hi BogyOne,
Try closing your client and deleting your WDB folder in the main WoW directory. This will clear your cache and can solve a lot of issues.
In regards to creating a bug on the bug tracker, you must be signed into the website (not just the forums - the forum and website accounts are not linked) and you will be able to create a bug report.
If you need a GM in-game, use the "Stuck" > "Still not working. Page a GM" option.
