I've been running WordPress at http://www.drewvogel.com since June 2005 on my FC5 box but since installing 2.0.4 I've been having trouble in the following areas:
1. The ability to post comments seems to have disappeared. If a user visits a single-view page, the comments dialog ... just isn't there. Even for me as admin, it's not there.
2. I've got my Permalinks set to Custom and "/index.php/%year%/%monthnum%/%day%/%postname%/". As long as I do not visit Options->Permalinks, my site functions as expected. However, if I visit Options->Permalinks, my site's permalinks stop functioning unless I set them to the default (I don't even have to click "Update Permalinks Settings"; just visiting the page breaks it), which breaks internal links in my site. This is 100% reproducable.
I've replaced the classes.php and functions_post.php files with the latest copies in this thread (http://wordpress.org/support/topic/54340/page/2?replies=52) and done all the steps here: codex.wordpress.org/Permalinks#Fixing_Permalink_Problems . I've followed all the steps on http://codex.wordpress.org/Permalinks#Fixing_Permalink_Problems , but my .htaccess is still never updated.
3. I've got WP-Cache (2.0.17) installed on my machine, but I'm not sure if it's working or not. From Ricardo's documentation and my own previous experience, I expect that WP-Cache adds two lines to the bottom of cached pages: "This first time WP-Cache will add a line with the total time needed to create the page, if the page is directly served from the cache, it adds a second line telling it was served from cache.". However, on my site, only the first line is added ("<!-- Dynamic Page Served (once) in 0.484 seconds -->"), but the second line is never added and the cached pages just pile up in /wp-content/cache.
These are extremely frustrating issues! Can anyone help with any of them? Thanks in advance!
