XF 1.5 Problems with upgrading from version 1.5.5 to 1.5.6

Problems with upgrading from version 1.5.5 to 1.5.6
I've already downloaded the upgrade file multiple times
And many times copied the contents and overwrite the old files.
The only thing that I get to see pre and after the upgrade, the following two messages.



There are at least 1 file(s) that do not appear to have the expected contents.......

Which file???

Typically this indicates issues with uploading the files.

If you have cPanel, I recommend uploading the zip archive and extracting directly on the server.

Otherwise you will need to upload the files again.
Don't use Filezilla if you are using it as we have had numerous reports of problems with it. I recommend WinSCP.

I'd note that it mentions upgrading to 1.5.5. That should only appear if you aren't running 1.5.5 yet. It does look like the files uploaded are for 1.5.5 based on the version in the top left.

If you have an opcache that isn't checking for changed files frequently, you may need to manually tell it to look for updated files (or restart your web server/PHP process manager).

Brogan and Mike,

Thank you for your outstanding support.
I actually make use of PHP OpCache. After restarting the server, getting the upgrade.


Thank you guys !!

I actually completely missed the fact that the screenshot was stating 1.5.5.

I knew there was something amiss but didn't quite make the connection.
