[Forum] 4.1.9 to 4.1.11 Upgrade Start Up Error

[bf777]

When attempting to upgrade from 4.1.9 to 4.1.11 I'm not able to upload index.php which results in the following error when I attempt to upgrade.

Due to the following errors, the install/upgrade can not continue:

• Following is a list of files that are either missing or contain unexpected contents. The most likely cause is that all of the files from this release have not been properly uploaded. You should resolve this error before continuing.
  /index.php - File does not contain expected contents

What am I doing wrong?

This is my first time attempting to upgrade myself.

Do you have a custom index.php file? Is there something special about the one on the server?

If your site was working, you can probably skip the error and move forward. You should that option at that screen, I believe.

Custom as in do I have code added to it, for example for mods? Yes, I believe I do.

Well, I just manually uploaded all the items in the upload folder and was somehow finally able to upload index.php without receiving an error message. However, at the upgrade menu, I'm still getting the same error.

Well I figured it out. After uploading index.php a few times the upgrade finally went through. Looks smooth so far.
