Ghost in the machine may be right!
I don't think the permission error is ever given because of a post's contents. It's an error which checks the user's permissions to access various parts of the blog. It could be a funky screwup with cookies, that's my guess. But a ghost is as good a guess as any. :)

interesting - I can also add this.

We've experienced this problem from multiple users, logging in from different computers, in different locations, using different browsers... Mac - Safari, Windows IE.

So that would rule out a local browser thang.... methinks.

Has anyone experienced anything like this?
Want to rule out any .0.9.2 bugs.

it also "feels" like it could be server related?...but whut?

the seemingly random nature is the killer..

Is the text that causes the problem a title or content? Either way try using the exact same sentence only put a dash inside a word here and there to see if any specific sequence of characters is causing the issue. I've only a small idea of why I suggest this, and am not sure it'll help, but it won't hurt.

Way back in the day when I had a blog post with the word "limit" in it I found I could not post it. I forget the error, but the problem turned out to be that "limit" is an official commanding type of word in MySQL. I posted it with "lim-it" in the title and was happy. That bug might have been resolved - I just don't know.

Anyway I see the word "create" and wonder if that's freaking it out. In the first sentence it is before a period. In the second it is after. I have no clue if that matters, but PERHAPS this method can get more info for you.

Bravo EdB - thanks for your time.
Wow.
You are INDEED the guru.

Create - damn it.
That is it exactly.
The word Create.

So then... what is the fix? ... since this is a difficult word to obliterate from a Fine Arts web site.
:o

So "fine arts" and "create" are sort of related eh? And here I thought "copy/paste" was fine art... ;)

Was the text part of a title? In my case with "limit" it certainly was part of the title, though it appears it was not used in the text of that particular post. Searching my hackblog via my back office shows me 22 matches for "limit create" with OR selected, and I recall this problem with one specific post, so I'm feeling like it's an issue with titles only. If the problem shows up with specific terms in the post content I wonder if it has something to do with location inside the text, meaning before or after some sort of punctuation, assuming the issue shows up with post content containing these 'official' words, but I digress. Over the course of my life I've managed to master the fine art of digression, but that too is not exactly topical.

In my case I left the title of the post alone - visitors see the word "Limiting", but I edited the field called "url title" under the post text window in the 'advanced properties' section. I simply replaced "Limiting" with "Lim_iting" and the problem was solved.

Hopefully this helps!
