LuxCal 5.3.1L - Invalid calendar ID after upgrading

If you have the SQLite version of the calendar installed and after upgrading you get an "Invalid calendar ID error, this can be solved as follows:

• In the database folder (default "db") change the uppercase characters in the database file name to lowercase characters
• In the lcconfig.php file in the calendar root folder, if uppercase characters are present in the default calendar name, change them to lowercase.
• Start the calendar (just once) with the ?cal=<calendar name> URL parameter. Where <calendar name> is the calendar name changed above.

Thereafter the problem should be solved.
