Make sure that line (1558) doesn’t have any spaces after the last letter of code.

If you have a backup of that functions file, you can replace the bad one with the good one.

Whenever you make changes like that, you should make them to a child theme so you don’t lose your changes when the theme gets updated.

Are you still having a problem? Your site comes up fine for me, though a bit slow. The page is about 1.5MB, so that isn’t too unusual.

When you tried your test comment, were you logged out at the time?

Anything you write when creating or editing a page or post in WP is going to be inserted within the #content div. So yes, that ID will pertain to those specific elements of your site. (Other elements such as widgets will have different IDs, if any.)

Again, best thing is to use the aforementioned web developer tools of your browser, inspect the element you’re interested in re-styling, and copy (or otherwise match) the existing selector string of that element in your new child-theme style rules.

thematic_abovefooter() is an action hook found in the theme’s footer.php file. You may find a function inserting content into that action hook in the theme or child-theme functions file.

EDIT: too slow once again 😉

Wish I could be of more help, but I think your best bet is to keep following up with the theme authors. There’s a lot of extra functionality built into that theme, and then with other plugins on top of that, it gets hard to untangle. Let us know how it goes, and good luck!

I get the feeling something may have happened to the wp-config file.

There isn’t much in that file by default except your database connection info (unless you’ve added some stuff to it), so if your posts come up OK on the front end it’s probably OK. But you can easily compare it to the sample wp-config included in a fresh download and scan for anything unusual. (see: http://codex.wordpress.org/Editing_wp-config.php#Default_wp-config-sample.php )

One thing to look at concerning those permissions quirks before doing a manual re-install: take a look at the permissions settings of your WP files and folders on your server. You can use an FTP client (like FileZilla), or your web-host’s cPanel or file manager to do this. (Or easiest: ask your web-host to check them for you.) Typically directories (folders) are set to 0755 and files are 0644. These are common settings for a shared-hosting environment, but check this page for your specific setup first.

I would go ahead and take a site backup now anyway, even though it may contain errors. Database too. Chances are most of your files are fine. If your permissions look good, I still think re-installing WP is not a bad idea, just to get a clean start there. Just be careful about the files I mentioned in my prior post and be methodical and you should be fine. Let us know what you learn.

I can’t be sure, but I’m guessing that you may be using WP eCommerce for your inventory display and sales? If so, try asking about this on that plugin’s support forum for best results.
