White Screen when not logged in - SMF 2.0.17

[izotz]

I had my moderators editing new post titles containing special characters for the last while to avoid this error.
I think my database is ok, but I can't tell for sure what to do about it, or how I can tell it is ok or not, or how to do it.
Any idea if this would be fixed with the recent upgrade to 2.1.1?

I don't know if this will be helpful for anybody, but I think this has not happened to us after we upgraded to 2.1.x, so I assume it got fixed.

Thanks for all the hard work!

Please do not resurrect 2 year old topics...  the original problem described here was fixed by upgrading ....   and, as I said in your topic -- by correctly converting to utf8 instead of hacking the system because you dud it wrong in thr first place.
