Windows 10: Squiggley red lines are back again

I recently replaced my 10 year old desktop and I'm having problems with my word processors. I have OpenOffice and LibreOffice installed. I use LibreOffice to convert my old .wps files and O.O. for everything else. This has been working very well for me until a couple of days ago when suddenly every document had red "squiggley" lines under almost every word. I have a file with all my passwords and, of course. spellcheck nailed them. I'm trying an operation that someone on the O.O. forum told me. They gave me a phrase "appdata" etc...can't remember the whole phrase. You then copy the phrase, paste it into the search box (Cortana) and it takes you to the O.O. folders. You are supposed to rename the folder and this will resolve the red line issue. I had the same problem with the laptop I'm on right now, but once the issue was resolved, it stayed fixed. On the desktop, as soon as I can rename the folder and start opening files, O.O. has already created a new folder called user. I talked to some people on the O.O. forum who said this issue was caused by shutting the pc down to fast, but that's not the problem...already tested. Apparently I have not found the right person on O.O. forum to help me. Perhaps someone here will be able to give me some advice. Thanks.

I was typing a comment to a news article must have hit a key by mistake red line under letters or when I hit the space bar a red line comes out.

I was typing a comment to a news article and must have hit a key by mistake, a red squiggley line started, it

looked like the misspelled red line, but even when I hit the space bar it produced a red line, there was no grammar

error. I was using Microsoft edge on windows 10.

Thanks I believe I answered all the questions you had for me but if I missed 1 let me know.

I just realized I am typing now and it has quit, let me check it out. Looks like it's working.

I sure do Thank You!

 

Red Line in text- NOT in Word

And the annoying line isn't showing in my screen shot! What's up with that? I wish I knew what I was doing to get the red line and I would do it again. I will keep trying to get the red line back.
