[For 1.8] MyBB-PageManager

[AlmostElton]

Hello,

I installed recently on MyBB 1.8.30, and I can't seem to get the plugin to display. My server specs are below:

Apache Version 2.4.52
PHP Version 7.4.28
MySQL Version 5.6.41-84.1
Architecture x86_64
Operating System linux

Is there a compatibility issue? My error log is not showing anything relating to the plugin, but obviously there's still an issue somewhere. Thanks for any help.
