The Error Log function is used to show the last 300 errors generated by a website, which could create unexpected problems in its management (pages not displayed or generic errors). The function is very useful to understand, for example, if there are errors in some CMS (Joomla, WordPress or others) plugin or incorrect or non-existent links within the website.
It is a tool often used by webmasters who carry out frequent maintenance and / or updates on their portals, showing errors in chronological order.
