Running upgrade to 2018-04-22b leads to following:
1. Output ends with:
All files updated
Deprecated inc/plugin.php deleted.
Upgrade complete. Enjoy your new DokuWiki.
But I get a popup reading "parseerror".
When I click ok, I get another popup reading: SyntaxError: Unexpected token < in JSON at position 0
Then clicking ok again, I get the following error:
Warning: require(/Library/WebServer/Documents/dokuwiki/inc/Plugin.php): failed to open stream: No such file or directory in /Library/WebServer/Documents/dokuwiki/inc/load.php on line 110
Fatal error: require(): Failed opening required '/Library/WebServer/Documents/dokuwiki/inc/Plugin.php' (include_path='.:') in /Library/WebServer/Documents/dokuwiki/inc/load.php on line 110
I then find inc/Plugin.php is missing. I then copy it into place from a zip of the downloaded clean DK. The wiki then works.
But 2018-04-22b is NOT installed.
Can someone please help me understand how to fix this?
