Some of my users break b2evolution when they try to post, tho some can. Others cannot post unless I give them the privileged blogger level, though the privileges were set the same as in another site I'm running, tho I tried increasing them to use the blogger level. Here's the set of messages the nonfunctional privileged bloggers get when the try to post:
