Joplin for Desktop v 1.4.19
Windows 10 Pro Build 18362.19h1.....
Before I installed the desktop version, I was having the same problem with the Portable version.
Hopefully, there is an easy fix for this.
I do not synchronize with any other computer or device.
The last time I used my Joplin, everything was fine.
I opened it today and all my note titles had cryptic "code" showing instead of Titles. The code reflects the "*.md" file names instead of my titles.
After messing around with it for a bit, I decided to install the Desktop App and maybe that would fix my problem. After the install, I went to File, Import, Markdown Directory and imported all my notes.
Same result with note titles replaced with long, cryptic file names.
It has been four hours and no help.
Maybe I need to explain better:
This is what I am seeing in my "Editor Viewer"
Any help would be appreciated.
