In the neighborhood, stopped in to see how's things. Looks like forum isn't sending topic notifications. You're logging a lot of errors again, over 800k in forum log for 30 days, lot of database errors. Server log is almost 2.5 GB (yes, that's gigabytes). Don't have anything that will open a file that size, I'll delete it and see what's currently being logged. Will take a look at the database if my access is still good.
Can't get into cpanel, login info is ng.
