My b2evolution Version: 1.9.x

Last night when I went to bed it was working, but today when I get up my pages won't load. It looks like it's trying to load but it just hangs there, only a blank white page shows. I can get to the admin panel and I also used phpMyAdmin to repair and optimize tables in case that was an issue but it didn't fix the problem. Could anyone please help me?

Update: After leaving it trying to load while I went to take a shower it finally loaded. No other pages on the server are taking this long. I don't understand why this is happening. I went back and uploaded my last "safe copy" of my _main.php to see if any edit I had recently done might have broken it. It's the exact same loading situation with the safe copy though.
