What do I do?

[Crescent Pulsar S]

I was uploading chapters of a story to FF.Net's "doc manager" when I was given this message for two of them:

Processing Error

You are attempting to submit a HTML file but it does appear to be a properly formatted HTML file.

If you continue to receive this error, please forward your file to site support for further assistance.

Well, the problem persists. Problem is, I don't see how or where I go about "forward your file to site support."

While I can paste the chapters in successfully, rather than uploading the files, it doesn't keep the < and >, and I'd rather avoid having to replace them for the two longest chapters of my story. It had been a big enough pain adding tags to every paragraph when the story just exceeded sixty-thousand words.

Try using another file format for uploading to simply circumvent whatever the problem is?

I always used .odt for example.

I have no idea what that is, or if it's a format I can use with wordpad.

I think .odt stands for Open document Text kinda like saving as a pure text file only a bit newer.

It´s the standard text document form for OpenOffice and replacement LibreOffice...
https://en.wikipedia.org/wiki/OpenDocument
https://en.wikipedia.org/wiki/OpenDocum ... processors

Essentially it´s the fileformat for the free and open source replacement for MS Office.
https://en.wikipedia.org/wiki/LibreOffice

And wordpad supports it(though just minimally) ever since windows 7.

Libre office is free and also includes all other stuff that might be useful from MS Office, like spreadsheets and all that. And i´ve started to find spreadsheets rather useful for keeping track of complex numerical stuff for when writing.
Very useful and as its both free and open sourced, there´s not really a reason not to have it.

MS keeps trying to make MS Office look different and all, but mostly they´re just messing it up more for every new version(that usually breaks backwards file compatibility, unlike the .odt which remains the same). Last i looked there was just a small number of very specialised functions that MS Office had that LibreOffice does not, and they´re nothing i´ve ever needed.

I think .odt stands for Open document Text kinda like saving as a pure text file only a bit newer.

More like a free version of the .doc rather than .txt. If you look at a .odt file with a hexeditor it mostly looks like mashed up nonsense, like a .doc does, instead of the more or less raw text that you get from a .txt file
