The MultiSite Fix has a problem in Atahualpa 3.6.7, which is fixed by BUGFIX 367-01 and BUGFIX 367-02.
However, BUGFIX 367-03 should NOT be used AFTER installing the MultiSite Fix.
If you use the MultiSite Fix be sure you do the following in any order:NOT BUGFIX 367-03.
BUGFIX 367-03 is already included in the MultiSite Fix / Easy Header Fix (in the MultiSite code).
If BUGFIX 367-03 was previously installed it is ok, because the MultiSite Fix will overwrite it.
Do Not install BUGFIX 367-03 AFTER you install the MultiSite Fix, it is not needed and it will cause the MultiSite Fix to fail.
