On the wiki I am admin of w:c:ktane, I am having trouble posting on the discussion page.

When I try to post a reply or heart an item, it says that the action failed.

A bar appears at the top, saying "Action X failed", like "Undeletion failed", "Save Reaction Failed", "Saving Post Failed."

How can I combat this error? Should I just spam the submit button until it works?

Or is it something about me doing too much too quickly? What is the limit, and how can I disable/increase it if I don't like it? I am admin, I should not have these restrictions.
