Error in kile about unable to open PDF file

I’ve been having a problem with kile and for a long time, I’ve just ignored it but it’s now getting annoying…

While typing in the editor window, I get a message that says, “Could not open file:///tmp/kile-livepreview.RDNKpj/p.pdf”. So, when I look for this file, I do have permissions to access it — it is the PDF version of what I am typing.

The other strange thing is I only have the editor open; I’ve closed the preview window. So, I guess there are two issues:

1. Why is it generating previews when I didn’t ask it to (has it been turned ‘on’ somewhere which I don’t know about?)?
2. How come it’s complaining about access to a file which I clearly have access to? Both the file and the path to the file is accessible by my user ID.

Also, it doesn’t happen all the time. Only sometimes…I cannot figure out the pattern of when it appears. Maybe once every 5 minutes as I type?

It’s somewhat annoying that this error pops up while I’m typing. Has anyone experienced this and/or know what I should do?

This is Ubuntu 19.10, so kile is version 2.9.92 .

Thank you!
