I have been trying to upgrade EE 2.8.1 to 2.9.0 but the Update Wizard just loads for a very very long time and then gives a 404 error.
After trying this a couple of times I removed the “installer” directory. CP now says “2.9.0” at the bottom, but it also gives this warning:
Your ExpressionEngine installation’s version (2.8.1) is not consistent with the reported version (2.9.0). Please update your installation of ExpressionEngine again.
Has anyone else experienced this? How can I get the Update Wizard to finish completely or find out why it hangs?
