Brian, hello. We've talked before.
I'm doing a new installation for a pro-bono site for a local scout group.
I made certain to upload the files in ASCII mode. Chmod the config.inc.php and showCalendar.php to 646. chmod the database directory to 777.
in browser, went to mydomain.com/escal/setup/ created password, logged in, and started modifying. when i changed the esdates.txt to 13swdate.txt and saved the error message showed up.
I tried using the database option first, but ran into problems as it would not recognize the user I set up. I'm no expert at php, but I can read and understand it better now.
couldn't find the problem.
don't know what else I can do.
