Thread:Project:Current issues/Errors after upgrade the PHP to 5.3 FastCgi/reply (4)

Why did you re-install MediaWiki? That is not necessary. :-)

If you want to continue with the new installation, import the old DB with MySQL. Either via phpmyadmin (if you have that) or maybe even better using the command line like so:

$mysql -u myuser -pmypassword -h myhost dbname < backup.sql

Just import your old database that way.

However, all that would not be needed, if you - instead of making a new installation - just updated your old installation: Install the new MediaWiki version and remove this PHP file called profiler.php (or profiling.php or so) in the root directory. Then run the MediaWiki installer. It will update the database to the new scheme. No broken links or so afterwards... :-)
