I have the same problem here:
"An error was encountered
Error: Unable to fetch search index words."
My version is: 1.2.12 and the url is http://familiabuchmann.isgreat.org/gene … ?mod=punbb
It happens just when using brazilian portuguese characters like: é á ã ç ó. When a user try to insert a topic or a reply, without these characters, the system works fine.
All my sql's table statement are: UTF-8.
Please, help me to correct this problem quickly. I set my forum as "maintenance" for this reason... anyone can post in brazilian portuguese, our mother language.
Another problem: "Rebuild index" and "Update forum sequence (0, 1, 2)" aren't working. When clicking it opens another strange page (not error) and the rebuild or sequece foruns update didn't happen.
