Local plugin: install and uninstall error

Local plugin: install and uninstall error

Hello, dear community.

I created local plugin. And I added db for this plugin. After adding db, when I try to install or delete this plugin, I see error:

"Cannot read file. Either the file does not exist or there is a permission problem."

This error shows already after actions(install, delete), when press button "Upgrade Moodle database now".

When plugin worked without any tables in DB - errors wasn`t.

How I can fix this problem? Maybe need add some more data about table?

Thanks a lot for help

What Debugging level is Moodle set to? Change it to "Developer" if it's not already set to that. It might give you a more useful error message, like which file it cannot read.

Have you updated the \local\your_local-plugin\db\install.xml file with the correct database structure info?

With install.xml all is normal.
