Introduction An XML Sitemap is required to allow search engines to easily crawl and index your blog. As a full-time network engineer and hobby blogger, I had not much time to build my own sitemap. So, like all blog folks out there, I used plugins to generate it. This article shows you how a simple XML Sitemap error can hide more that you think. XML Sitemap error I got since more than 3 months a weird XML sitemap error message: XML declaration allowed only at the start of the document XML declaration allowed only at the start of the document I first thought it was due to the Yoast SEO plugin. Therefore I deactivated the Yoast-generated XML sitemap. deactivating yoast seo xml sitemap and installed another sitemap plugin which generated a correct (at least to my eyes) XML sitemap. However, Google search console still flags my blog as Soft 404. I spent whole weekends and vacation days trying to reverse engineer the reason behind this Google rejection. blog pages are excluded from google A...

You can ignore the message and continue to the next menus. The Postman dashboard will load normally.

Firefox is a popular browser used by more than 11% of the Internet users around the world according to Wikipedia . I still use it for regular Internet surfing. A nice Firefox feature I like is window tabbing. However, a while ago I noticed that, each time I press “CTRL-T” to open a new tab, I get “www.google.com” in it. And that’s annoying because I often times copy a URL and quickly want to paste it in the new tab URL field. Restoring the default blank page on Firefox I tried to change the settings in the Options menu –> Options. But it seemed like Firefox did not take it into account. The solution I found was to play with Firefox variables: In the Firefox URL field, type about:config A warning message displays. Hit “ I’ll be careful, I promise ” In the Search field, type “ browser.newtab.url ” and hit Enter. You’ll see that the value field displays “www.google.com” double-click on the entry. In the Enter String Value , type “ about:blank ” and hit Enter. Now the browser.newtabl.ur...

You’ve taken beautiful photos in your vacation and you want to go straight to the photo where you have the Eiffel Tour behind you. But all your photos are named SAM_xxxx and you don’t know which one you must click on. What’s happening? It’s not a problem on your machine. It’s simply a Windows default behaviour. In fact, Windows 7, by default, does not display picture thumbnails. Instead, it displays icons. It’s not really a useful setting from Microsoft. But it can be corrected. Hopefully this little trick helps you display thumbnails of your photos and videos. Here’s how: Go to Start –> Control Panel, In Control Panel, go to System In System, go to Advanced System Settings Go to Performances and click on Parameters Under Visual Effects tab, search for Show thumbnails instead of icons and check the box Click on Apply Once you have done that, all your pictures will be visible in thumbnails.    

Months or even years after you bought your last computer, it seems there are some programs that make your computer boot slower than before. A simple and free tool to use is Microsoft Windows Msconfig. This command allows you to control which programs and services run at computer startup. How to use Msconfig I am using a French keyboard by the way. Go to Start then type this command: msconfig A System configuration window opens. In the fourth tab, uncheck all the programs you don’t want to load at startup. For example, I have Winamp that starts with Windows. I simply uncheck it and click on Apply . Windows asks you to either restart your computer or close the window without restarting. I prefer the second option.
