You are welcome.
Sometimes it gets tedious when people expect me to solve things that I have no control over and who become agitated with me because of things that involve typical internet activity that they don't understand and are frustrated about, but I can't say it is a thankless chore now.
I checked everything that I could check on my end. It is working. Alert users would have caught me going to that very thread and posting "test" on it several times.
They couldn't have noticed when I went to optimize the database. That was another thing I did.
I also went over logs to see if there is anything there that might indicate a problem.
I found nothing. And I was at work (real job, ya know) and had to, well actually work.
I don't think the technical explanation makes any difference to you and I think that ultimately you just want it to work but I'll now explain why it's out of my control:
The "no post mode specified" error happens when the "mode" variable in posting is not set.
For example, the post page for this thread is:
posting.php?mode=reply&t=20430
The posting page handles many different types of actions. A post to a thread is one mode, quoting or editing are other modes.
When the page does not receive the variable for "mode" it gives that error.
Try it:
http://www.able2know.com/forums/posting.php?mode=NOT_A_REAL_MODE&t=20430
It won't work. That is not a defined variable in the array.
It will give the same error.
Now all the posting works off the same file, so your ability to post here indicates to me that you can, in fact, post to Able2Know.
So what can cause a specific thread to do this?
I do not know. It works perfectly for me.
What I guess at is that you have a faulty URL for some reason. And that if you simply surf to it using the URLs that the forum software provides it will work perfectly.
Or perhaps you have the posting page cached but with an error.
I do not know. I can only guess, from halfway around the world.
Your information about opera is a different one altogether.
That simply indicates that the internet connection was lost. This is common on the internet and also beyond my control.
Perhaps connectivity issues prevented you from posting and if you try again all will be well.
Again, I just can't know.
If it is either of the things I describe it should work in subsequent attempts.
Now I know it'd be nice if stuff just worked. But you are not tossing me an easy problem. There are things that happen on the net that I can't solve.
Sometimes things are beyond my control.
I spend a good deal of time investigating this problem of yours during my lunch hour.
Did you try (or even investigate) anything I recomended (like getting a fresh URL for the thread)?
I know that all you want if for me to magically make it right. And I'm sorry, but due to the nature of the problem you presented I can't do that.
What I have control over is working just fine.
Could you try to post again? Because if all this is about a transitive problem (as I suspect) then it's just a matter of a bit of patience till it works.
What I control I fix when it's broken. What is out of my control I can only make a best effort at.
You need to help me resolve your problem. It is working when I do it and across the world it's not working for you. This isn't one of those times I can snap my fingers.
Try it again for one. Don't use any saved URLs and navigate to the thread through the board. Let me know if it is working.
