Latte dock on Kubuntu does not auto started any more

I had installed latte-dock ver. 0.8.9 and it worked fine before. However, due to some mistaken configurations during applying new plasma look and feel themes I decided to uninstall Latte and the reinstall it again.

Currently, Latte does not be started automatically on login. I always have to press ALT + Space to invoke the search app and start it manually.

I have tried the following:

1. Uninstall Latte then reinstall it after restarting the computer.
2. Check/Uncheck Enable autostart during startup from Latte Dock Settings.
3. From the terminal I checked out latte-dock --replace and I got the following output

Invalid Context= "animations" line for icon theme:  "/home/x/.local/share/icons/Oranchelo-Beka/animations/22/"
Invalid Context= "panel" line for icon theme:  "/home/x/.local/share/icons/Oranchelo-Beka/panel/22/"
Invalid Context= "panel" line for icon theme:  "/home/x/.local/share/icons/Oranchelo-Beka/panel/16/"
Invalid Context= "status" line for icon theme:  "/home/x/.local/share/icons/Oranchelo-Beka/status/scalable/"
Icon theme "gnome" not found.

where x is the username

4. Also I tried to add autostart entry from system settings

Update

The following is a screen shot from KSystemlog where it shows some warnings during starting Latte

This question is pretty old now, but I just had a similar problem. My situation was also self-inflicted (accidentally deleting ~/.config !!!) The Latte Dock had been previously installed and working.

The fix for me was to clear the Latte cache. Running latte-dock --help shows the command options: --cc or --clear-cache:

latte-dock --cc

After that, the Latte Dock was just fine. It now loads during session startup.

P.S. I also see a lot of Invalid Context=... messages for icons. They're annoying, but seem harmless. I suspect it's just some installed icons (for gnome) that aren't Plasma-friendly. In fact, I came across this post while looking for a way to eliminate those messages!
