WordPress.com Login Loop

Sometimes, when I try to use certain functions on wordpress.com, I get redirected to a login page. After I sign-in, I get redirect again to the same login page. This repeats in an endless loop. It usually doesn’t bother me, as I self-host my blog, but for some things, like the yearly annual report that came in about two weeks ago, it does bother. I looked up into the matter, and the issue turned up to be due to blocking third-party cookies. To resolve the endless login loop, you need to add https://wordpress.com (note the https) to the exception list of accepted third-party cookies (In Firefox it’s under Preferences -> Privacy -> Exceptions).

Incremental WordPress Backups using Duply (Duplicity)

This post outlines how to create encrypted incremental backups for WordPress using duplicity and duply. The general method, as you will see is pretty generic, and I’ve been using it successfully to backup also Django sites and MediaWiki installations. You can use this method to make secure backups to almost any kind of service imagineable: ftp, sftp, Amazon S3, rsync, Rackspace Open Cloud, Ubuntu One, Google Drive and whatever else you can think about (as long as the duplicity folks implemented :-)). If you prefer a simpler solution, and don’t care about incremental or encrypted backups, see my Improved FTP Backup for WordPress or my WordPress Backup to Amazon S3 Script.

Improved FTP Backup for WordPress

This script backups both the database and files of a WordPress blog into a remote FTP server (while keeping a local copy). It’s an update of my WordPress Backup to FTP script. The main changes are auto-detecting database settings and better support for caching plugins (specifically WP-Cache). The new version makes it easier to backup multiple WordPress blogs to the same FTP server.

Sociable Plugin Doesn’t Play Nice

I’ve been using the Sociable plugin for adding easy “share” links to the bottom of my posts. Up until yesterday I’ve been using the 2.x versions of the plugin, but yesterday I’ve upgraded to 3.4.4. Today I’ve noticed to my surprise that the plugin automatically adds a box to my admin dashboard with “The Latest news from Yoast”, Yoast beeing the plugin’s maintainer, Joost de Valk, blog. The plugin itself doesn’t feature any way to completely disable this “feature”. One has to hide it using the dashboard settings. While this may seems benign, in my opinion its pushing the limit. If I’m interested in getting updates from that blog, I would sign up to its RSS feed. I don’t like getting “free” functionality not advertised in the plugin description.

I must add that as a user of the Sociable plugin, I’m more than satisfied. I probably won’t stop using the plugin just because of this issue, but it still seems to me like improper manners.

WordPress Backup to FTP

Update: A newer version of the script is available.

This script allows you to easily backup your WordPress blog to an FTP server. It’s actually a modification of my WordPress Backup to Amazon S3 Script, but instead of saving the backup to Amazon S3 it uploads it to an FTP server. Another update is that now the SQL dump includes the database creation instructions so you don’t need to create it manually before restoring from the backup.

Although I’ve written it with WordPress in mind (to creates backups of my blog), it isn’t WordPress specific. It can be used to backup any website that consists of a MySQL database and files. I’ve successfully used it to backup MediaWiki installation.

Clean URLs (Permalinks) for WordPress on Lighttpd

I’ve moved my blog in the last few days to a new bigger dedicated server (as well as some other sites I own). After doing some benchmarks (I plan to post those soon) I’ve decided to switch to Lighttpd. While the exact migration notes are the topic of another post, I can say that I’m fairly satisfied with the move.

After setting up the server, I started moving the blog. Importing the files and the database was pretty straight forward. But when I thought every thing is ready and I transfered the domain to the new server I’ve found out that none of my inner pages are accessible. The reason, as it turned up pretty quickly, is that the WordPress depends on Apache’s mod_rewrite to create the clean URLs (the so called permalinks). This actually posed two problems:

  1. WordPress depends on Apache’s mod_rewrite.
  2. WordPress used .htaccess files for the clean URLs configuration

WordPress Backup Script

This is a small script I’ve written to automate my server-side backups of my blogs. It creates a backup of both the database and the actual WordPress files.

#!/bin/bash

# This is a script that creates backups of blogs.

echo -n "dumping database... "
mysqldump --user=${DB_USER} --password=${DB_PASS} --host=${DB_HOST} ${DB_NAME} \

if [ "$?" -ne "0" ]; then
	echo -e "\nmysqldump failed!"
	exit 1

echo "done"
