Help with likely error messages

hi,

i am a new user and would love to actively take part in this web community. However, I am continually having a problem "posting new posts". I guess you understand what I mean regardless of the unlikeliness of the grammar. As i was saying, I have a problem making posts and keep receiving this error message:
The following error or errors occurred while posting this message.

This message shows without explaining the error encountered and how to fix it.

I would really love for the site managers to create an avenue on how to solve error messages and what to do when a member encounters a particular error message as well as likely error messages a user can encounter.

Thank you.
