I followed this tutorial
https://www.phpbb.com/support/docs/en/3 ... web-server to create a phpBB forum on my localhost. I did this yesterday but when I logged in today, I got an error called "Fatal error: Uncaught Error: Call to a member function getParameter() on null in C:\xampp\htdocs\includes\functions.php:2999"
I also had a problem with MySQL shutting down but I fixed it by following the top answer on this link
https://stackoverflow.com/questions/180 ... expectedly. This might have something to do with my current problem so I included it just in case.
I have attached a screenshot of the error. I am a complete newbie at phpBB and Xampp so I would appreciate any assistance or advice you have.
Thank you all and I look forward to hearing your replies!
Update: I deleted all by phpBB files from the XAMPP htdocs folder and redownloaded them and it worked for a little while. However, as soon as I sign out of the device and sign back in, the error came up again.
