Update 4.7.18 via Admin Panel fails

[NZyan]

I just tried to update from 4.7.17 to 4.7.18 in multiple forums.

All of them failed with the message „There was an error downloading the files to your server.“

As update only the full download is available which takes ages to upload and compare to the server.

Is a version of the update available that includes only the changed files?

Now one of the installations offers the download only of the update – but the link only opens an empty page without download:

https://remoteservices.invisionpower.com/download/ips_71b57/?version=107774

Update: Results in Error 500

If you are having issues with the files being downloaded automatically, you need to download a full set of files and upload these to your server, then run the upgrade

Hello!

I have the same problem.
I downloaded the whole set of files, uploaded them but still having an error in the attachment. I can't get past this even though files were re-uploaded properly.

@Marc gave the crucial tipp in another thread:

1 hour ago, Marc said:

Add this to a constants.php file. Its important you remove this after the upgrade 

<?php
define('UPGRADE_MD5_CHECK', false);

 

You have to put the constants.php in the server root.

Maybe you have to start over once or twice from the Admin panel.
