WYSIWYG tinymce editor unwanted tags showing in drupal 7 I have css define set and themes/garland  in the input for the directory but when I go to test all tags are showing.

Do I need to deselect an option in buttons to stop this or is it something else?
Sounds like a text format settings issue, review the formats at

Admin > Config > Content authoring > Text Formats

e.g Filtered HTML > Limit allowed HTML tags

and add the allowed tags if necessary.
