Yes, we have created the '$wgBugzillaChartStorage' 'charts' folder w/ proper permissions for the apache2 server.

However, if trying to get charts working, bar or pie, we either get the error:

" Bugzilla query error
Notice: Array to string conversion in /srv/www/jogamp.org/mediawiki-git-1.32/extensions/Bugzilla/templates/error.tpl on line 5 error, http-bad-status, Array"

or the resulting images are corrupt / buggy.
