Re: Unable to insert search index words

In my experience, these kinds of errors have only generally happened when you've meddled around with the search index php files. You haven't installed any forms of mods on your forum at all, have you?

Re: Unable to insert search index words

You can try to rebuild the index on the Administration -> Maintenance page.
