I upgrade all slave server on my clustered setup, not by runnging the ispconfig update script but by removeing all dbispconfig db and ispconfig user and also /usr/local/ispconfig, and do a new install of the latest version. What happens i after each server install , then i add is to the panel , but there's the problem, the existing detail on the panel cannot replicate to the slaves, either i did not finish the update or anything like that. Then lastly i update my panel server a i did above, and here is the main problem, i use tar pcf to zip my ispconfig folder but when run tar zxvf file.tar.gz it result with un recoverable message .... in addition to that after dumping my dbispoconfig db to the new emtpy dbisconfig db and access to panel webpage ... their's whole lot's of php code appear even i cannot logi .... anybody have any idea before i redo my whole setup ....... ????
