An error log is a list of the error messages and warnings which showed up for one reason or another while your visitors were surfing around your website. This sort of a log includes raw info about the way the hosting server has handled requests in various situations. An error message might appear if, for instance, a link leads to a webpage or a file that isn't on the hosting server, if the code on a certain page cannot be processed, if any individual is trying to access the site or its back office through an IP address that is blocked by an .htaccess rule and so on. The info inside the error log features the IP address of the website visitor, what error message appeared and the basis for the web server to show it, the whole path to the file that induced the error and the specific time of the event. Having this info will enable you to figure out if any part of your website has an issue, which you could then resolve. As a result, your website visitors will have a better experience and you may supercharge the site for maximum performance.
