Cache won't invalidate

Hi,

 

I'm running MidCOM 2.2.1 on Midgard 1.6.1 on an up-to-date Gentoo box. From
this list I determined that if I set a site setting for localication to
en-us that my dates will print out in the desired format.

 

However, now I get all these cache warnings:

Notice: Undefined index: en-us in
/var/local/cache/midgard/22-90-15-0.php(307) : eval()'d code(58) : eval()'d
code on line 56

 

I have delete all rows from the cache table and all files from
/var/local/cache/midgard with no change. I have run
http://test.quicktricks.org/midcom-cache-invalidate and it doesn't solve the
problem either.

 

Any suggestions on how to fix this?

 

TIA,

Alan
