Hi,
(I’m French, so please excuse my English)
I had the same problem after uploading some new manager themes and trying them.
I’ve tried the following :
- Logging out / in (actually, rebooting my browser because the logout link was no more visible ) -> No effect
- Kind of panicking a bit
- Reading this thread
- Updating the value of ’manager_theme’ in ’modx_system_settings’ table to ’MODxLight’ (default theme) in the DB via phpMyAdmin -> No effect, updating it back
- Hardcoding the value of the $tplFile variable in /manager/includes/accesscontrol.inc.php (line 128) with the name of my newly uploaded theme -> No effect
- Realizing that the login.html file of my theme was a 0 bytes file on the server, re-uploading it -> This was the error, it caused filesize($tplFile) to have a value of 0. I thank Filezilla and my web host for its great connection

Everything’s clean now, however I don’t understand why updating ’manager_theme’ in the DB had no effect. It might be a problem of cache or something like that. Anyway, thank you for your help.
