I keep getting an error message.

Just FYI.

i just tried to edit a post of mine as well as i wanted to add something to it instead of double posting, and got the error message too

For a long time now, I've found that my posts don't show the icon denoting a youtube link unless I go back in to "edit" - even if I don't actually change a thing - and then save again. After editing once, the icon shows in the forum.
But I also wasn't able to edit yesterday, so my most recent post still doesn't show the camera icon.

I've resolved that error that you guys were seeing. Also, the site now accurately reflects if the original message or any replies has a Youtube vid in it, and puts the icon up next to the post on the main listing. It wasn't adding the icon if the video had previously been shared on the forum, but now it shows the icon no matter what if there is a video.

I'm getting an error today:

Fatal error: Call to undefined function multidimentional_sort() in /home/messmeup/public_html/post.html on line 1058

Anything I can do?

I believe I've fixed that. Can you see if you are still seeing that? And if so, what is the post you're editing?
