I'm in panic...
don't panic ;-)
I made an error when changing a site access rule and this caused ZMI to be not available. So I can't undo tat through the ZMI ! How to undo the latest transactions from command line ? The bbb.py provided with Zope plays only with ZODB2 files (in fact it's useless till it's not upgraded)
To quote form SiteAccess' documentation:
In particular, Access Rules and SiteRoots trigger whether you want them to or not, and I've had to tell many a panicked email correspondent how to disable one or the other (put _SUPPRESS_ACCESSRULE or _SUPPRESS_SITEROOT in the right place in your URL) because they were locked out of their Zope.
AFAIK you could also use the SUPPRESS_ACCESSRULE environment variable Bye Erich -- Aufgepasst - jetzt viele 1&1 New WebHosting Pakete ohne Einrichtungsgebuehr + 1 Monat Grundgebuehrbefreiung! http://puretec.de/index.html?ac=OM.PU.PU003K00736T0492a
