@Erin: You don’t need to log into your WordPress blog…you need to log into your database using phpMyAdmin.

I’m freaking out. I tried to install Buddy Press (FAIL) and got this:

Fatal error: Call to undefined function get_blog_option() in /home/erinweed/www/www/wp-content/plugins/buddypress/bp-core.php on line 566

The video is nice…but I can’t even log in to my site! I just get the above text on a white page. Help!

Are you sure you didn’t replace the index.php file when you were uploading other files? Also, did you get the plugins you added deactivated?

I have a very wierd problem. I don’t quite know what I did but for some reason the whole website is just blank. I can’t even log in because the login page is blank too, everything has stopped working. I thought it was because I tried to install a couple of plugins but that didn’t seem to change anything.

I was uploading things into the publicHTML folder also but I don’t remember doing anything out of the ordinary.

Would appreciate the help.

@Mike
There are several related posts plugins out there…I use this one: http://mitcho.com/code/yarpp/

I don’t think it creates a new db table, but it does add a lot of rows in the wp-options table. I would expect, that if you properly uninstalled the plugin that it would remove the db entries, but that may not be the case. You may want to look and see if the plugin created new tables in the db…if not, then look in your wp_options table for any rows it created. If you find any…delete them. Backup your database before doing any of this.

Thanks,
I have a related and weird problem though:

I installed a plugin called ‘related posts’, but didn’t like it.
I deactivated the plugin correctly, but my single post pages still show related posts. In addition I used your method in the video to be sure the plugin was dead, but my ‘related posts’ now has a life it’s own.

Can someone advise me on how to remove the remains out of the MySQL database. I would’know where to begin looking/editing through PHPMyAdmin.

Thanks,

Mike
