Windows users may experience an issue when creating a database with an error message of "ERROR: SQLSTATE[HY000][14] unable to open database file".
The reason that you’re seeing that error is probably because of one of the reasons below:
1) You are on Windows, and that either the database name, or the path of the database, contains non-latin letters. Try creating a database with latin letters only in its name, and make sure its path contains only latin letters.
2) You are on Windows, and your user name contains non-latin letters. This is because when you create a database, Pagico will also attempt to initialize your Inbox database, which is stored in your user data folder. In this case, you’ll have to rename your user folder before you can continue. Here’s a tutorial on how to do this:
