This question may be related to a resolved thread.
I upgraded my installation from 2.4 to 2.5.1 on my local machine and got a strange blank screen after running the wizard. If I deleted the “installer” folder, I was able to resolve admin.php. But once that happened I got the message that the installation version (2.5) was different than the reported version (2.5.1). Going into config.php, I saw that the version number was indeed 250, so I changed it to 251 and the message went away.
Should I be worried about that?
Thanks in advance!
