end tag for %1 omitted, but OMITTAG NO was specified

Cause:

You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

Example:

textexample textexample

Bad:
textexample textexample
Good:
textexample textexample

Solution:

textexample textexample
