I was able to post, but all my paragraph indents went away. (I do know how to use them, honest!)

I have not now (nor have I ever) encountered any issues in posting, commenting, editing or any other function(s) associated with iModeler. I can only assume that any problems in those areas lie within the user's connection(s) and not the fault of the site. I'm by no means an IT tech, it's simply my .02 on this matter.
However, as a caveat, it does seem that several people have had (or have now) the same problem. I guess everybody can't be wrong. 🙁

@craigindaytona thanks for the info. Yes the source of concern here is that two users are experiencing the same issue at the same time. Luckily the majority (including our developers) seems to have no problems, but all together this makes the source of the issue that much harder to locate.

I am repeatedly asking @robertandy and @gkittinger for help testing this or that and thereby trying to narrow down the problem. At this point we have also pretty much done all we could on the server-side, sans the total rollback of a major upgrade, something that we are reluctant to do without knowing the exact cause.

In all, please bear with us.

Thanks for info, @shoobiz. I have PM'd you with request for further details.

Good news - it would seem that we have located the source of the issue for @robertandy, @gkittinger and @shoobiz.

The problem occurred like this: for whatever reason, just after the last upgrade (and the previously described glitch in the system) our automated spam filter started to identify these users' IP addresses as potentially unfriendly and therefore kept pushing all the submitted comments to the spam folder. In human terms there was no reason whatsoever for this action, but spam filter is a machine and we DO need it :/. It is just the case where it's learning algorithm went astray.

The bad thing was that:

• No error messages were issued to the users... (note on this taken)
• This has been done to the registered users who have previously been cleared for comments (should be fixed by now)

I was now able to recover all the messages that had ”vanished” (should be online now),
and Greg and Robert have reported being able to post again.

So - happy commenting everyone. Please let me know if there are any outstanding problems.

No problem posting, but why are there several articles from December 2012, by Bill Weckel, making the rounds again?

Aha...THAT explains it. I was wonderin' 'bout that. I answered his posts anyhow (I can't remember what was posted in 2012 - I can't remember what happened last WEEK). 🙁
