Choosing the theme for your WordPress website is one of the most important and most difficult tasks. You will find a plethora of themes to choose from, and getting that one theme that will work wonders for you can be quite a challenging task. But, just getting a good interface is not enough while choosing the theme; you will need to test the theme and check for existing bugs also. You will need to make sure that there are no bugs present in the theme selected.
You will need to conduct the theme through three different phases before you actually come to the conclusion that it is a WordPress bug free theme, and you can release the website based on this theme. Remember, if there is a bug, there is a fix for that bug too. You will need to quality check the whole theme and finally make it complete with quality.
