As stated in the title, I'm in the process of upgrading a site from EE1 to EE2, and I'm encountering errors on Wygwam's settings page. This is almost identical to the issue Lisa raised, with the exception of the line number in error #3 being different.
Errors 1-3 are all above the CP menubar:
A PHP Error was encountered
Severity: Warning
Message: base64_decode() expects parameter 1 to be string, array given
Filename: wygwam/helper.php
Line Number: 40
A PHP Error was encountered
Severity: Warning

Line Number: 42
A PHP Error was encountered
Severity: Warning
Message: array_merge(): Argument #2 is not an array
Filename: wygwam/mcp.wygwam.php
Line Number: 302
Errors 4-6 are immediately below the "Wygwam" heading (the one with the pencil graphic on the right-hand side), above the Preferences table:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: base
Filename: views/index.php

The EE 1.7.1 site had Wygwam 2.6.3. The upgraded EE 2.5.5 site has Wygwam 2.7.
