First off, please forgive me if this is posted in the wrong place. I am trying to install WordPress under Ubuntu 20.04. I followed the instructions in this link https://linuxconfig.org/ubuntu-20-04...e-installation. Once everything was installed and configured I opened my browser to 127.0.0.1 and received the following error message: PHP installation appears to be missing the MySQL extension. I've done Google searches on how to resolve the problems which has to do with outdated extensions, but I haven't found a solution that I can understand and follow. Please let me know if there is any additional information I need to supply. Thank you in advance. Scott
