I checked my site this morning and was presented with a ton of errors, rendering the whole website pretty much useless. The main error seems to be:
WordPress database error: [Duplicate entry '30280' for key 1]
SELECT DISTINCT YEAR(post_date) AS year, MONTH(post_date) AS month, count(ID) as posts FROM wp_posts WHERE post_date < '2005-08-10 10:56:35' AND post_status = 'publish' GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC
as well as these errors for my Poll:
WordPress database error: [Duplicate entry '30280' for key 1]
SELECT id, question, total_votes FROM wp_pollsq ORDER BY id DESC LIMIT 1
WordPress database error: [Duplicate entry '30280' for key 1]
SELECT aid, answers, votes FROM wp_pollsa WHERE qid = ORDER BY votes DESC
I'm still pretty much a WordPress novice and I have no idea at all about what these errors means. I've used MySQLAdmin to repair the offending tables, but this hasn't helped. Any help would be hugely appreciated - thanks!
