Thread:Project:Support desk/PHP version error when upgrading from 1.17 to 1.21/reply (3)

Hi!

You do not have to tell the wiki, which PHP version to use, but you have to make sure that on the server the right PHP version is run.

You sound like you are not on shared or managed hosting, but you have complete control over the server. I think you missed to make the new PHP version the one, which gets executed, when the server starts. Often that is done with a service. You run a service, which starts PHP. Change this service to start the new version instead of the old one. Maybe it also makes sense to uninstall the old PHP version.
