Commenting Errors Persist
Okay, I’ve filed a “help me now, please!” ticket with Movable Type. Sorry for the problems! Please keep trying — avoid the preview if you have trouble — and know that I will update you as soon as I’ve heard back.
Special thanks to Joe M. for his help and patience.
Update: Movable Type says:
We have received another recent report of this behaviour in Movable Type 3.31 and 3.33, and were able to reproduce it with the default [JavaScript] templates. A case for this issue has been filed with the developers, so that they may identify and prioritise any possible corrections for a future version. At this time we have no information to provide you with regard to any corrections or alterations you might make to rectify this behaviour […].
They suggested dropping previews and using another preview plug-in as a workaround, which I’ll explore ASAP. Another update as soon as I can. Thanks!
