Hi, I just went through all the process of https://www.libreoffice.org/bugassistant/libreoffice/bug/bug.html?version=5 and I'm stuck at description. No field is red, nothing indicates what I should do, and there is no submit button. Great. If you want to get bug reports, you should probably fix this.
I’ve just tested and the Submit button appears fine (just below the “Explain what is attached” field). Please file this issue at https://redmine.documentfoundation.org along with a screenshot and your system and browser details, if you can reproduce it consistently. This is not the place to file website-related bugs. Thanks!
