Hello. On our roundcube installation I see the following error. When I send message, roundcube hangs with status "Sending message" for several minutes. Then I receive "Request time out". However, the message is sent. It's related to spell checker. I see that after sending message our roundcube host opens connection to spell.roundcube.net (443 port) and they are talking for a second:

I've inserted several debug messages in rcube_spellcheck_googie.php and now it looks like

     $url = rcube::get_instance()->config->get('spellcheck_uri');

     if ($url) {

Looks like some problem with our server, but Thomas is on vacation this week. Better configure Roundcube to use local spell engine (php-pspell/enchant).

I took a look at the server, and it's having some unexplained segfaults in libaspell. I upgraded some packages (including libaspell), but that didnt fix it. I think i'll leave it up to Thomas to check out further. This does mean the spell service provided by rc is currently not working correctly, possibly only for some languages.
