Been getting a whole bunch of these lately when I click on links to forums or Today's posts...get blank page with Critical Error and that the site is having technical difficulties and to check back in 24 hours, but if I retry the link a few times, it comes up again. The forum has been really flaky as of late but I am sure you guys know! Similarly, I have found that searching for old posts is nearly useless as if it doesn't have the old posts indexed? fyi
