Hello, My site https://plastifikacimetala.com/ is no longer working because I updated SP Page Builder Pro. Please help me to restart the site. Thank you. I also want to install investa_quickstart_j4_v1.0.2 on localhost (I use xampp-windows-x64-8.2.12-0-VS16-installer) but I get the message MySQL server has gone away, what should I do?
