The subject line captures it all. Visiting http://localhost:8090/ (where I always accessed the old version) gives a blank screen now. I don’t recall if I had a success message during the upgrade. Apache error log shows nothing untoward but for each attempt to visit the above URL results in an entry like this in the access log:
::1 - - […] “GET / HTTP/1.1” 500 -
How do I troubleshoot/ fix?
