Rainloop Issues

I have loaded latest release of Rainloop on a fresh install of CWP. It ssetup to access local postfix/dovecote mail server on same box.

Everything appeared to be working fine. Incoming email loads no issue and testing connection settings for the domain in the admin area everything lights up green.

However, when I try to send or save a new email the Icons flash red and get a message saying Can't send or Save.

I have checked permissions/ownership and all seem fine and I can't see anything obvious in the logs which I have turned on. I tested turning off the Firewall but issue remains.

To be sure it wasn't a mail server issue (rather than Rainloop) I setup a remote mail server in Rainloop but I still get the same issue.

Anything obvious I'm missing as I'm new to CWP?

Thanks

I also having this issue and all works fine just the annoying message keep popping out say cannot move.

Got to the bottom of this in the end. Its was mod_security rules blocking things.

As soon as I turned off mod_security it was fine. When I have some time I will go through and work work which rules and being triggered and disable them for the roundcube directory.

same problem here.
reinstall is my solution.
save
/rainloop/data/_data_/_default_/domains
/rainloop/data/_data_/_default_/configs
reinstall.
then put those files back
