An error log is a list of the error messages and warnings that displayed for one reason or another while your visitors were browsing your site. This sort of a log contains raw info on the way the server has handled requests in different situations. An error message could appear if, for instance, a link leads to a page or a file that's not on the hosting server, if the code on a given page can't be processed, if any individual is trying to access the Internet site or its back office via an IP address which is blocked by an .htaccess rule and so on. The data inside the error log includes the IP address of the visitor, what error message appeared and the cause for the hosting server to display it, the entire path to the file which triggered the error and the precise time of the event. Having this information will allow you to figure out if any part of your website has a problem, which you can then clear up. Consequently, your website visitors will have a better experience and you may supercharge the Internet site for maximum performance.
