Just thanks to @user062 for passing me the new database structure of the paid versionGuys the error is because we have updated the database structure as is the original plugin from the developer.
That's why trying to import the old data can have problems.
I made the previous database according to the queries made by the plugin.
This new database is just like a paid version but being nulled (obviously you can't use the standard apps)
But if we want to have the new features it was necessary to upgrade to the new database structure since we are already in version 6.0
Unfortunately we have to add our accounts from 0.
In order to prepare for future updates.
The database structure we had was from version 4.0 adapted to new versions.
Don't throw stones at me, I just nulled
In short, if you want to keep the previous version, there is no problem.
But they will have to add their accounts from 0 at some point for future updates.
This will serve us well for future fs poster plugin updates.
