I do not know
try to wait if someone can help you
hahahaa... I know, everyone will be hungover look at this issue.
^ tested it on a local test board. plugin is working.
I also tested it on the same theme. m.
and the same version of MyBB localhost. This plugin works.
but when I tried in hosting this plugin does not work properly.
I was also surprised by this incident.
it appears that plugin's code <!--PostbitTags-->{$post['tags']}<!-- /PostbitTags--> is missing in postbit_classic template
try the same right templates "postbit" equal "postbit_classic"
thank you for your help. m. and SunDi3yansyah
