I'm Unable to Comment on Discussions

I literally can't post comments on any of the discussions from my computer. I've tried logging out and back in and I've also tried restarting my computer. I can still navigate and update my wedding info. This is the only site and the only thing on the site that is giving me issues. Obviously I'm able to continue on like normal on my phone but I have no idea why this is happening. Anyone have a clue?? Can it be fixed??
