I was writing a post, on a pc, that was like bit bit bit bit bit, and then all of my post was gone... and I was like... ¿uh?
It devoured my post. It was really good post. And then I had to write it again and had to do it fast so it wasn’t as good.
It’s kind of... a bummer.
The Preview worked, but the post was never submitted.
After losing a couple of posts this way I now always, if it's anything other than a trivial post, copy my answer to the clipboard before I click on "submit". That way, when it jams up again, I can refresh my browser and paste the text back in to recreate my nearly lost post.
I've also had it log me out while I'm typing up a longer post and then when I submit it complains about me not being logged in and I lose the whole post...
Perhaps it would be better if it didn't wipe out the textbox when you hit submit, so if it took a long time and seemed to be hanging you could copy out your post and reload the page.
It doesn't happen to me (I'm more prone to somehow lose focus of the textbox and press backspace) but I am somehow in the habit of Ctrl+A,Ctrl+X,Ctrl+V-ing my posts before I send them, just so I visually know I copied them and that I can paste them back if needed.
So when you copy the post content that doesn't work and Ctrl+Shift+R the page and try again, it still doesn't work? This seems a different issue than what I have experienced occasionally.
I don't think the post content should affect being able to properly send it unless some party between you and this website is blocking certain character combinations. At least, from what I know of how this works, it shouldn't matter what your post content is so long as it isn't too long, but I'm no expert.
Had a similar issue (said "Sending please wait" but seemed to have frozen), but I closed that tab and opened the forum up in a new tab and saw that it went through. I haven't had any issues with tags though.
I have also been noticing another (seemingly similar) issue, quite often I will be trying to load a page on this site and it hangs and I either have to stop and reload or close that tab completely, open a new one and come back. It only seems to be this site (I can open Google and do searches fine, I can go to my school's website, login to my account and access various services just fine).
Considering that this seems to have to do with the length of your post and the specific content of your posts, don't you think it's possible your ISP, router, or some other thing between your computer and cplusplus.com is interfering? Perhaps antivirus software not liking javascript that posts content?
