I'm getting an error "WordPress database error: [Table 'jcherfas.wp_posts' doesn't exist]" in my sidebar. But the posts certainly show up in the main content.
I checked with phpMyAdmin and indeed there are no tables by that name. They are called jcherfas_weblog_wp_links. Oh, and under Manage Links, they show up fine.
I cannot think why the prefix should have changed. I added slimstat last night, but that did not involve touching the WordPress files except for the header in my theme.
Any suggestions?
