An error log is a list of the error messages and warnings that appeared for one reason or another while your visitors were surfing around your Internet site. This kind of a log features raw information about the way the web server has handled requests in various situations. An error message could appear if, for example, a link leads to a page or a file that is not on the hosting server, if the code on a given page cannot be processed, if any individual is trying to access the Internet site or its back office via an IP address that's blocked by an .htaccess rule and so on. The information in the error log offers the IP of the site visitor, what error message displayed and the basis for the web server to display it, the full path to the file that generated the error and the exact time of the event. Having this info will permit you to determine if any part of your Internet site has an issue, which you can then clear up. Therefore, your site visitors will have a better experience and you may supercharge the Internet site for best performance.
