I am getting this error

I’m getting the same error. Has anyone come up with a solution?

I’m also getting an error when I try to post (after having run the upgrade.php script). The error I get is as follows:

WordPress database error: [Table ‘dbname.wp_post2cat’ doesn’t exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM wp_posts p LEFT JOIN wp_post2cat pc ON p.ID = pc.post_id LEFT JOIN wp_categories c ON pc.category_id = c.cat_ID WHERE post_status = ‘publish’ GROUP BY cat_ID

I upgraded via Fantistico via my host, BlueHost.

Before I upgraded, I had no problems posting to WordPress.

Read the “sticky” post on the main page of the forum: incompatible theme or plugin.

runningblogfather – does that message appear every time you post or just sometimes? Are you using suphp? Are you using apache and mod_php?

jnagyjr – that error isn’t related to WP Super Cache ??

I receive this error sporadically. It was almost constant at first. Now it occurs on the first saves (and continue), but likely not with the second. I can’t really find a pattern–whether it happens only when the content changes or whatnot. It’s more likely to happen after I wait a bit, as well.

jpelker – is your host on an NFS server, and are you using flock? You should try semaphore file locking if you are.

@donncha:

I’m trying to pry this info from my web hosts and I’ll keep the thread notified once I find out the deal.

Just wanted to update that I also see errors on comment posts:

From the host:

“There is no nfs on the server.

Please take a note that we do not support 3rdparty software and don’t do any script reconfigurations.

You can upload your custom php.ini file that contains your custom php settings.

Please take a note that it should be put in every folder where php scripts are expected to be run.

We can upload a sample of the php.ini file to your public_html if it’s needed.

Thank you for your cooperation.”

Just edit the wp-cache-phase2.php file, find the “unlink()” command on line 433, and stick an @ in front of it. Like so:
@unlink(whatever);

Problem solved. You’re getting the warning because it’s trying to delete files that don’t exist. Well, okay, I don’t know why it’s doing that, but it’s not exactly an “error”, is it? The files don’t exist and it wanted to delete them. Seems like a non-problem, eh?

Just add the @ to suppress the warning and get on with life.

Cue Bette Midler…

Did you ever know that you’re my hero? You’re everything I wish I could be. I can fly higher than an eagle because you are the wind beneath my wings.
