It's strange. I have two wordpress installatations with identical plugins with the same hosting company. One works fine, but the other http://www.grancanarianow.com has problems. I have a database error every time I post e.g
"WordPress database error: [Can't find FULLTEXT index matching the column list]
SELECT MATCH(post_content, post_title) against ('test') as score FROM wp_posts where id=116;"
which I posted about a few days back and doesn't seem to affect the final outcome (all seems ok from the front end), though you have to go back to the front page to get back to the dashboard (I don't get the problem if I edit and re-save). De-activating plugins doesn't solve it.
BUT now the first users are joining, two out of three have complained that their emailed passwords don't work. I changed the password for one of them, and that still didn't work. Deletion and re-registering did.
So there are glitches somewhere. Are they related, and is there anything I can do to sort this out before other users (I won't necessarily know who they are, as anyone can register) have similar problems?
Or should I back up the posts, delete and start again? The site isn't meant to be a short-term thing.
