I recently tried to migrate the web page to a new joomla version. Somewhere in that process things turned to the wrong side and as a result, the web page was corrupted. Attempts to rebuild the database from the backup failed, so unfortunately, the only option appears to be rebuilding the web page from scratch.
This is the process I now just started and of course I am applying some changes I wanted to implement for quite a while.
So stay tuned and come back soon to see what is new!
