How to format columns in Libre Writer 6.0

I have used Libre Writer successfully and joyously for the past couple of years in publishing a monthly 12 page newsletter. I recently had to reset my computer to clear unwanted stuff and lost Libre Office obviously. I downloaded the latest version Libre Office 6.0 and find that I cannot format my page for columns. I cannot do a newsletter without columns. what’s the solution…? Thanks…

Which OS do you use? What does “cannot format” mean? How are you doing exactly? Please describe your procedure and when does a problem arise.
You can try to reset your user profile:

to create columns, I go to format, scroll down to columns and choose columns, two, three, etc. cant do that with writer 6.0

You should use menu FormatColumns.

This command was temporarily removed for 6.0 (and introduced back in 6.1); it is equivalent to inserting/formatting a section with multiple columns. In 6.0, use InsertSection..., FormatSections....

The other option, FormatPageColumns, does a different thing: it changes formatting of the active page style, thus making all the text that sits on the pages with that style to have (at least) the columns configured there.

You can get what you describe more than one way.
I imagine you will want a single column heading at the top of a newsletter so I suggest:-

  1. Put your heading at the top of the page
  2. On a new line below it, click on “Insert”>“Section” to open a dialogue box where you will be offered a name for the section, probably “Section 1”. You can change if you wish.
  3. Click on “Format”>“Sections”. Select the section you want to adjust. Then, “Options”>“Columns” to obtain a dialogue box and set up your columns as you wish.

The new section will expand to accommodate the text you enter.
To save the trouble of doing all this (and more) for every issue of your newsletter, I suggest you create and save a newsletter template. You can find advice on this in “Creating a Template” on page 217 of the LO 6 Writer Guide. You you can download this, free of charge, as a PDF from the LibreOffice Documentation Page.
