In order to use the underscore symbol with this issue, use the ASCII symbol (_) instead of the underscore.
For instance, you would use new_user_login instead of a new_user_login.
Hope it helps!
Hi! Igor Popov!
I am moved by your question, especially about the time stamp URL and author manifestation XML.
Would we have a some talk or exchange of info about this? It's been 4~5 years since you issued that question. My e-mail is email@example.com...For the sake of keyword searching in the amara-embed-iframe I need your advise. God bless U!!!^-^" From Seoul, Korea
