If you are a web developer then you will be familiar with the term bugs in a website. Bugs are parts of the website that are not working correctly, and this can happen for a number of reasons.
Often bugs may just be a simple bit of code that has been mis typed or placed in the wrong area. Hours can be spent trying to find out the problem and sometimes to no avail.
To save time which in turn saves money, you need to try and find quick and easy methods of identifying bugs to allow you to sort them out quickly. There are a number of ways in which you can do this.
Firebug (part of Firefox browser) is a free plugin which allows you to pick apart code on the website to see how it works or how it can be fixed. It also allows you to make live changes (local only) to the code to see if you can fix it. Once you have found what the issue is you can then apply the correct code to the code on the live version of the site. This also allows you to play around with colours, fonts etc without having to do it live for any visitors to see.
IF you are using an off the shelf system such as WordPress or a bought theme then you may be able to contact the developer for support or post on a forum to get feedback from other developers as to what the issue may be.
