Thanks for responding so fast. Hopefully we’ll find some solution. Take note however, that I’m close to being code-illiterate (I do most of my coding by trial and error, so speak with capital letters to me, as we say here in Poland. ??
Here are the cPanel error logs, YARPP enabled, trying to enable WP-PostRatings or WP-pagenavi, result the same:

So it refers to the following lines in the class-admin.php:
// new in 3.3: load options page sections as metaboxes
require_once('options-meta-boxes.php');
67108864 bytes seems like… well… way too much. Until now I’ve been using the same combination of plugins for years now, including the two (three actually) I’m unable to turn on simultaneously right now. There must be something new.
