Upgrade

• DokuWiki Upgrade
• finding different files

$ find . -type f | while read line ; do diff ../dokuwiki-2020-07-29/${line} ../rostin-stage/${line} &> /dev/null ; if [[ $? != 0 ]] ; then echo $line ; fi ; done

• deleting files listed in data/deleted.files

# cd dokuwiki-2020-07-29
# grep -v ^# data/deleted.files | while read line ; do if [[ -f $line ]] ; then echo $line ; rm -f $line ; fi ; done

• if blank page is displayed after upgrade, there is likely a problem with some extension. Inspect /var/apache2/2.4/logs/error_log Apache error log to find out which extension is problematic and remove it from lib/plugins/ directory. Then re-install the extension(s) again after upgrade is done.
