Due to the wide variety of possible problems, it is often quite difficult to locate the specific problem affecting a webpage. Therefore, people ought to develop a procedure for when problems occur in order to reduce the stress of locating the problems. In most cases, it is best to start by validating the various codes in the website design.
Greater complexity in the website also complicates troubleshooting. Any sort of server script or dynamic element needs to be troubleshooted separately from the basic HTML code and can add much trouble to the process. Therefore, it is wise to test the site often so you can more easily identify the source of problems, thus dramatically reducing the time and headaches involved in troubleshooting.
In addition to coding problems, a website designer could encounter troubles accessing the site from the internet. This is usually trouble with the local Domain Name Server. If the domain your website is hosted on is new, its name has likely not yet been distributed to every Domain Name Server. This cannot be remedied by the site designer, but will resolve over time as the domain name is propagated to the Domain Name Servers.
There are also sometimes browser compatibility problems. This occurs mostly with relatively new browsers or browsers that are not widely used. Google Chrome, while a great concept, has caused problems with certain web applications. There are issues with every browser, but some are less obvious than others.
Other browser issues include cache and cookie problems. If the website requires a cookie to be on a user's computer and the user blocks all incoming cookies, the user will be unable to use the site properly.
