I did do a validation before posting, I should’ve mentioned that. Anyway, here’s the output of ./validate.php:
Component | Version

MySQL | 10.2.29-MariaDB-1:10.2.29+maria~bionic

Is there any particular item in the FAQ that you are referring to? Because I am not seeing blank pages, nor is this related to snmpd since the graphs show correctly after refresh. Or was that just intended as a general hint?
