Only a blank page starts

**satimis** · January 23rd, 2013

Hi all,

Ubuntu 12.04 desktop 64bit
Wordpress 3.3.1

I have WordPress installed locally. It was working and can be started on browser running /localhost/wordpress/wp-admin/

For unknown reason now it only starts a blank page.

I found some postings here on similar problem. Unfortunately none of them can help me out.

Please help. TIA

B.R.

It may be helpful to post any errors you see in apache2 logs.

In a terminal run:

Code:

tail -f /var/log/apache2/access.log

Then try to access the site, copy and paste the code ouput.

You can also do the same for error.log.

Several hours ago it still worked without problem. The nightmare started on installing the 'blackbird' plugin. Then I couldn't start it.

**volkswagner** · January 24th, 2013

This is more of a WordPress specific issue vs. Ubuntu Server.

Perhaps you may want to disable the plugin which likely broke WordPress. Check out this link on how to disable the plug without using the Dashboard. The example uses FTP but you can easily use ssh.

Pay close attention to creating a backup before you do more damage... you've been warned

Thanks for your advice.

This is a local installed WP. I haven't created any page yet. After installation I was playing around its features. Just started creating page by installing the plugin-blackbird. After finish it didn't showed the plugin on screen. Neither I could click backforwards. I started another page trying to login again and found a blank page resulted.

$ sudo find / -name plugins | grep blackbird
No output

$ sudo find / -name plugins | grep black
Also no out put.

Before installing this theme again. Is there any way checking the server here to find out any other possible cause making the installation fail? Thanks

One thing I should have mentioned was to check the permissions of the folder and files for the theme.

I'm not sure of any available precheck. As you can see now, it's not difficult to remove the theme if it does not work.

Perhaps try again. If it fails, check the permissions and make sure the files are readable by apache2.

OK, I'll retry.

What should be the permission of the folder, blackbird?

www-data root ? Thanks

**volkswagner** · January 25th, 2013

Compare it to your other working plugins/themes.

Likely www-data:www-data or yourusename:www-data.

I say owner as your username because if you are uploading via ftp this may be helpful.

Hi,

I wonder whether there is something wrong on the LAMP server here?

Performed following steps;

Download blackbird version 1.1.4 on;
http://wordpress.org/extend/themes/blackbird

# ls -ald /usr/share/wordpress/wp-content/themes/twentyeleven
drwxr-xr-x 7 www-data www-data 4096 Jan 23 17:19 /usr/share/wordpress/wp-content

(above confirms permission = www-data www-data)

unzip blackbird.1.1.4.zip

# mv /home/satimis/blackbird /usr/share/wordpress/wp-content/themes/

# chown -R www-data:www-data /usr/share/wordpress/wp-content/themes/blackbird
# ls -ald /usr/share/wordpress/wp-content/themes/blackbird

Code:

drwxr-xr-x 7 www-data www-data 4096 Jan  2 22:24 /usr/share/wordpress/wp-content/themes/blackbird

login WP

Appearance -> Themes
After playing around a while the screen became blank. Then /localhost/wordpress/wp-admin popup only a blank screen without Login page but without warning message displayed.

# rm -r /usr/share/wordpress/wp-content/themes/blackbird

Login page comes back.

I'll install a new WP on a VM of Oracle VirtualBox to check what will happen.

I followed;
1)
How To Install WordPress in Ubuntu Server 12.04 LTS
http://ubuntuserverguide.com/2012/05...12-04-lts.html

and

2)
Ubuntu Server Guide
http://ubuntuserverguide.com/2012/05...12-04-lts.html

to install WP here.

I hesitate whether I made a mistake on Step 4 of 2) above;

$ sudo bash /usr/share/doc/wordpress/examples/setup-mysql -n wordpress_preciseserver blog.preciseserver.com

In order to ping blog.preciseserver.com I edited;
/etc/hosts

Code:

127.0.0.1       blog.preciseserver.com  localhost
127.0.1.1       localhost.localdomain   localhost

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

on /etc/hostname

Code:

localhost

therefore;
$ hostname
localhost

$ hostname -f
blog.preciseserver.com

I'll follow another document;

and
