horde broken - Error connecting to IMAP server: [] .

[105547111]

Okay IMAP is working, my iphone and ipad can connect by IMAP and see emails.

Whats up with horde? I have not touched the server and its broken. As soon as you try to log in you get thrown back to the login page with the message showing after the last successful login time:

Error connecting to IMAP server: [] .

What is interesting is the last successful login time does increase with each attempt. So horde is now broken as it can't connect to a running IMAP server when nothings been changed!

The horde logs are full of these:

May 20 10:48:43 HORDE [error] [imp] Error connecting to IMAP server: [] . [pid 21901 on line 347 of "/usr/share/psa-horde/imp/lib/IMAP/Client.php"]
@ @

I also can telnet to localhost on the correct port as in a kb article found to test.

Also I ran https://webmail.domain name.com/imp/test.php and it says it's okay. I then test the user, password and server and it's all error free except the SSL test as the certificate is self signed, but passes the next ssl check without certificate test.

I have a feeling it was a plesk update that broke horde. I am running centos 5.6 x64.

Fixed!

In php.ini you have to allow:

escapeshellcmd popen

But now I also have to allow

fsockopen

Now it logs in again!
