) Yeyyy..... verry happy now...
So .. for the ones that first updated to SVN and after that t wanted to uprade to 188.8.131.52 and couldn`t because the database was screwd up.... here is the simplest posible resolution to that problem.
go to : http://domain.tld/phpmyadmin
login as root , select dbispconfig and you will see there 54 tables.... the new version of ispconfig has only 44 and as you try to upgrade the extra 10 tables screws you up. So ...u make a back-up to the database then u select the folowing tables : billing_invoice, billing_product, billing_service, billing_service_class, billing_tax, client_address_book, domain ,domain_handle ,domain_provider , domain_tld and u drop them (delete them).
After that you log in to console and update ispconfig :
and select stable version.
Hope this helps and on the future ...remember!!! Do not use SVN on production machines!!!
.... wait for stable
