An ordinary user does not have access to server files and will not be able to detect the cause of the error. But an administrator or web developer responsible for the state of the site is quite capable of diagnosing it. To do this, he can:
view error logs . Server software logs, i.e. records information about all events, including errors. Logs can be viewed in the site hosting control panel or directly connected to the server. Records can show when the error occurred and after what action it occurred;
check the .htaccess file. Errors and typos in this file are a very common cause of failure, and they are quite difficult to notice. It is better to check the file separately, see when changes were made to it, and, if necessary, roll back to the previous version. There are also special services for checking whether this file is correct;
use specialized tools. Sometimes utilities for log analysis and error search are available in CMS, website content management systems. But even if they are not there, you can install such software separately. And sometimes it is enough to view the information in the developer panel in the browser.
You can also check what version of PHP is installed on greece telegram data the server and whether any software has been updated recently. Perhaps a new module has recently been implemented on the server that conflicts with existing ones. Or maybe someone has mistakenly changed file permissions, and now the software cannot read them.
If you are a user, you most likely won't be able to do anything: the problem is on the site's side. However, you can wait for a while, reload the page, clear the browser cache and cookies . And if the error doesn't go away, contact the site administrators. Often their contacts are left right in the error window, for example, as a link.
