I have recently upgraded WordPress from 2.6.3 to 2.6.5. For first few days, the site worked perfectly. However, for last few days, I am facing two issues:
1. In the admin panel, the comments do not always load. It shows that I have comments pending, but when I click on the link...I an shown a message "No results".
Moreover, categories are acting wierd in the sense that when I go to <<Manage-Categories>>, the existing categories do not show up. Even, while writing a new post, the section to choose categories is blank.
I have "Statpress" plugin installed to check the visitors. Till 2 days ago, it was showing me the numbers fine. But since 2 days, it has suddenly gone blank. I check the error log in wp-admin and found a lot of error like this:
WordPress database error MySQL server has gone away for query SELECT count( feed) as rks FROM wp_statpress WHERE 1=1 AND feed<>'';
I also see similar errors related to comments. Further, approved comments have stopped showing in the posts itself.
2. The second problem is with the categories in the site. I use a magazine theme, in which I show the post excerpt for each category in the home page. Since the start of the problem, all these sections are blank with an error message "Not post found in this category".
To add to this, when I click on the categories in the website, i receive a blank screen in Firefox and HTTP 500 in IE. Fortunately the individual posts and pages seem to work properly. But, the "Latest Posts" section from the sidebar has also vanished.
I have checked with my hosting provider and have been assured that it is not a server issue. I checked the databases using myPhpAdmin and found all the categories in there. So they are not missing. Just not showing up in teh admin panel and with the permalinks also.
The above is a long list of issues that I facing...and after trying to figure what can be problem, now I am completely clueless.
Is this an issue with 2.6.5, coz I never faced this with 2.6.3? Any advice and a resolution with be really helpful. I get 60% traffic from search engines and they see the posts directly. Thats still good. But the rest is worrying me as almost 35% is direct traffic. If they keep on seeing blank homepage and category pages for long, I fear , i will lose them.
