Hello,
I copied the client site to my own test server to investigate the issue. I first installed 2.2.4 (since 2.2.10 doesn't exist in download area
). There I got these warnings:
JLIB_INSTALLER_ERROR_NOTFINDJOOMLAXMLSETUPFILE
JLIB_INSTALLER_ABORT_DETECTMANIFEST
It seems that some strings are missing from somewhere..
Then I installed 3.0.0 without warnings and the features seemed to work ok. Next I installed the 3.0.2 and again without any warnings and still the functions work fine. Perhaps there was something missing in SQL updating in 3.0.1 software package but was included in 3.0.0.
I will now take the client site offline and try this update procedure there too. Wish me luck..
