Hi, I have recently started working small time as a technician In a local school. When asked to make some changes to the school website which wasnt updated for some time, I decided to first update the WordPress Version it was using. To do so I used the Update function within the Dashboard and after few minutes the website went down with the Error 500 and I have no way of getting access into it.
What could be done to solve this problem? I have no prior experience with wordpress but according to several guides it could be a problem with a caching plugin or a corrupted htaccess file, but I have no Idea how to gain access back into the dashboard
