Confirmation

• I have read the FAQ.
• I have tested the latest development build of Holographic Displays and the bug is still present.
• I have updated Spigot to the latest release for my particular Minecraft version.
• I made sure the bug hasn't already been reported on the issue tracker.

Please update, you're using a version from more than 5 years ago.

I updated the plugins and the error started coming out I can't understand

You're still using the old version I think. The format of that file has changed. Also please do not manually edit the database.

Provide a copy of that file so I can try it (use Pastebin).

database.txt
here only the txt format is allowed

I'm not even sure how the YAML file became like that. The old version doesn't load it, even online parsers report it as wrong. You need to add single quotes (') at the start and at the end of each line.

Like this:

lines:
- 'Line 1'
- 'Line 2'
