Debugging JavaScript Code with Firebug
Firebug has become an indispensable tool for doing front-end development of web applications. However, most developers are unaware of some very useful features of this tool, especially when it comes to debugging JavaScript code. I've personally seen many of my colleagues relying on alert() function to reveal the flow of execution of their complex codes. In this article we'll look into some ways that Firebug can help you debug JavaScript and boost your productivity.Breakpoints Setting a breakpoint on a line enables you to pause/resume execution of code at your will. When you put a breakpoint on a line, say line 10, the program pauses execution when it reaches line 10. Let's see how we can do that:Turn Firebug on and enable Console and Script views. Then visit ajaxify.com. In the Script view, choose firebug.js from the dropdown menu at the top left corner. On the sub-view at the right click on Breakpoints pane. On the left margin of Script view, you will see the line numbers appear. Now click on line 10, it will be marked by a red circle. This red circle is the breakpoint, the Breakpoint sub-view will list you have set.Now refresh and hit the Change the Message! ...

Is the RSS Feed of your WordPress Blog Working in all Major browsers?
This morning one of my site visitors was kind enough to email me saying that the RSS Feed of my blog wasn't working on Internet Explorer and Google Chrome browsers. Internet Explorer is well known for its issues so I wasn't that alarmed but my hearth jumped as soon as I double checked the RSS feed on Chrome and found that it was complaining too. In this article I am going to explain what the error was and what I did to resolve it so you don't panic if it ever happens to you. The 1st RSS feed Error and Solution Internet explorer was displaying the following error when I clicked the RSS feed link on my site: The XML page cannot be displayedCannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later. Chrome gave me the following which was a bit better as it was pointing out the line of the error rather than saying there is an error: This page contains the following errors:error on line 485 at column 330: Encoding error At this stage my best option was to validate my RSS feed using the W3C Feed ValidatorA quick validation check ...

What Would You Do If Somehow You Lost all Your Blog’s Content?
I hope this doesn't happen to anyone else but this morning  my blog Tips and Tricks HQ somehow disappeared from the face of this earth! The day started as usual... I woke up in the morning went to my office and started checking my emails and found out that I received an email from SiteUptime (SiteUptime is a website monitoring service that checks your website at regular intervals and notifies you via email or SMS if it becomes unavailable) telling me that my site is down.So naturally I wanted to check if the site is up now. When I entered the site address in the address bar I got the following screen![caption id="attachment_959" align="alignnone" width="444" caption="WordPress Blog Setup Screen"][/caption]You can probably imagine that at this point I was pretty scared!

Not to mention the traffic that I am loosing now!Anyway, in my case the damage wasn't that severe.

How to Clean/Remove Not Found Errors from Google web master tools generated from translated versions
I installed a translator plugin on one of my WordPress blogs but the plugin wasn't working properly so I disabled it but two days later I found out that my Google web master tools account was reporting about 1100 'Not Found' errors under the 'Web crawl errors' section. All the errors were from translated versions of my blog. I used the 'robots.txt' file to fix this issue. If you don't know what a 'robots.txt' file is, then read the article titled how to control access of the web crawlers or web robots to your site.Basically, add rules to your 'robots.txt' file to Disallow any spider from indexing the translated version of the pages. My 'robots.txt' file looks like the following Depending on your situation you might need to block more languages. Just look in the Google webmaster tools and see which languages are causing the error then add them to the Disallow rule.User-Agent: * # Language pages Disallow: /ar/* Disallow: /bg/* Disallow: /zh-hant/* Disallow: /ca/* Disallow: /cs/* Disallow: /da/* Disallow: /de/* Disallow: /el/* Disallow: /es/* Disallow: /fi/* Disallow: /fr/* Disallow: /he/* Disallow: /hi/* Disallow: /hr/* Disallow: /id/* Disallow: /it/* Disallow: /iw/* Disallow: /ja/* Disallow: /ko/* Disallow: /lt/* Disallow: /lv/* Disallow: /mr/* Disallow: /nl/* Disallow: /no/* Disallow: /pl/* Disallow: /pt-br/* Disallow: /pt/* Disallow: /ro/* Disallow: /ru/* Disallow: /sk/* Disallow: /sl/* Disallow: /sr/* Disallow: /sv/* Disallow: /tl/* Disallow: /tr/* Disallow: /uk/* Disallow: /vi/* Disallow: /zh-CN/* Allow: /As far as I know, Google penalizes ...

How to Fix ‘Unable to create directory’ error when uploading image into WordPress
This post has a textual and video instructions showing how to fix the WordPress "Unable to create directory" error when uploading/inserting image into WordPress.I started getting the "Unable to create directory /wp-content/uploads/2008/12. Is its parent directory writable by the server?" error when uploading or inserting image into a WordPress post just after upgrading to WordPress 2.7. First I thought it is a directory permission related error so I tried changing the permission of my 'upload' directory to 777 but I was still having the same problem. After trying many things I was able to fix it using the following method.Log into your WordPress Admin account. Go to 'Miscellaneous' Settings options from the 'Settings' menu. In the Miscellaneous Settings put wp-content/uploads in the "Store uploads in this folder" text box. Save the Changes by hitting the "Save Changes" button and you are done.Fix WordPress Image Upload Error: Video InstructionsLet me know if this method worked for you.

If the privilege settings looks like the example shown below then your database import following the normal method is going to fail as it will try to create a database and you don't have permission to do that.[caption id="attachment_417" align="alignnone" width="192" caption="No privilege to create new database "][/caption]You will get the following error when trying to import the database file:#1044 - Access denied for user 'username'@'localhost' to database 'database_name'To get around this problem and to complete importing your database to your new host do the following:Login to your cPanel and click on 'MySQL Databases'.
