Tips on Trouble-Shooting WordPress, Plugins & WordPress New Version

Original Problem:
WOW! After I had gone through the trouble of create a SQL table for the Related Post Plugin and had it working. Somehow, my comments system is all mess-up. Wait, I had also tried WP-Cache, which doesn’t work too well. So, I think one of these two mess up my blog’s commenting system =(.

Update 1: It’s definitely the WP-Cache…Arg…Warning: it will change your WordPress core files!!!

Here are some helpful comments I got from a few of my fellow forumers’ posts:

“Beware of wp-cache. Many strange things have happened to blogs with that plugin installed. It might be better now since it’s been some time since I looked at it”
–Fellow Forumer 1

“The ‘headers already sent’ means there is some errant white space or typo somewhere in your code; best place to look is on line 86 in the seth godin plug-in. It’s likely not the MySQL table you installed.”
–Fellow Forumer 2

This is the error message that appear at the top of the header:

Warning: Cannot modify header information – headers already sent by (output started at /home/seoblogger/public_html/wp-config.php:2) in /home/seoblogger/public_html/xxxxxx/xxxx/what_would_seth_godin_do.php on line 86

Update 2: I took the liberty to UPGRADE it to newest version of WordPress, WordPress 2.2 =P. Took about 10 minutes but it works out–o.k. for now :mrgreen: .

Update 3: Everything is back to normal =P. Now, I’ll just have to upgrade the other sites :D …And I too know what’s wrong with the older version of WordPress. With the new version you have an ‘integrated’ widget file, so you don’t have to use the Widget Sidebar plugin, plus the ‘Preview’ at the bottom of the ‘Write’ area is taken out and replaced with a ‘Preview’ link on the upper right hand corner of the screen (but why took it out when I can use the Clutter Free Plugin to remove it + other ‘cluttering’?).

Here’s How I Trouble-Shoot This Problem:

I fixed this problem by upgrading to the newest version of WordPress (WordPress 2.2), since I think the WP-Cache change some ‘core’ files of the WordPress (don’t know which).

And yes, the pain of following the not-so-detail installation instruction at the WP-Cache website was unnecessarily ‘painful’!

I know the Related Post Plugin isn’t a problem because I have used it on my other sites.

After this experience and other near d(r)ead experiences from WordPress and third party plugins and WYSIW you don’t get editor, I humbly suggest fellow bloggers who use WordPress to BACKUP ALL YOUR DATA before activating a plugin!

And also, try to set up your blog with all the plugins as soon as possible, because you don’t want your blog to look ‘discombobulated’ when you have 1000+ visitor a day. Then, again, you might want to test ‘new thing’ on another site once you have that many reader .

*Note to yourself: when attempting to use/activate ‘just’ a plugin, BE SURE TO BACK-UP ALL THE DATA!

By the way, here’s a database managing plugin I use: WP-DBManager
