Seriously, all I did was the following:
- Copy the dist file in the managesieve plugin dir to without the extension; set the port.
- Add 'managesieve' to the array of plugins in main.inc.php
- Restart httpd
I double-checked. All the files are owned by apache. I can't login now, because I keep getting the same error displayed. Incredible. This can't be THAT fragile...especially since I'm pretty sure my syntax is perfectly correct, and I even tried commenting-out my plugins entry in main.inc.php and it still doesn't work anymore.
Please help?
