Overview:
I've upgraded to roundcube-1.1.5, but it is failing, and restoring old roundcube is not working.
In addition, after upgradeing iredadp, I also get an error.

** Thank you in advance **

specifics:

emailing from roundcube gui times out. Yet from mailclient, it works.
- I checked roundcube mysql access, and had to change the password, because 1st error was "cannot connect to DB".
- I lost/overwrote config.inc.php so added plain test password there.

for iredadp, the logfile show:
