Description of Problem:

If I'm not in creative mode, NEI and my inventory go blank visually if I open my inventory. This only happens on SMP. The items are still there if I click on them and know where they are.

You seem to have the NEI mob spawner bug ongoing. Disable the spawner subset, info here: http://forums.technicpack.net/threads/nei-common-problems-and-fixes.2206/

Did that, I'm a noob, but I'm a good noob and read the common problems thread. The issue returned even after I did that

Is the NEI search box at the bottom yellow? Try double-clicking it.

Ooh, that DID fix it Torezu, thank you. Wonder if that tip could be added to the common probs thread
