Hi, I've installed 3.1 yesterday, I had many problems since. At first it messed up some of the Apache vhost files, so nothing worked. I edited them or restored them from backup. Now the webs work, but I have a few other things: I get this error at least every minute (per email): Code: ERROR - MongoDB is down! Rescue will not help! But I have not installed MongoDB, I am using MariaDB. I get this error on every ISPConfig web page configuration page: Code: CONFIGURATION ERROR 2016-15-04 16:04 : Syntax error on line 105 of /etc/apache2/sites-enabled/100-*****.**.vhost: RewriteCond: bad flag delimiters Action 'configtest' failed. The Apache error log may have more information. failed! Websites are working, vhost files seem to be OK, the only problem is I get emailed a lot of error mails, because by every change Apache wouldn't restart properly, etc. Allthough it is working, this is rather annoying. 3. I am generating my Let's Encrypt certs with ./letsencrypt-auto certonly, standalone server, the I symlink the certs and copy the keys to the right place in ISPConfig. I think they don't really work though, because I either get some errors, or I load a page with domain xxxx.yy, but I get shown the page aaa.yy, because that was the first one with an SSL cert on my server - completely different domain! Not for every domain though, some of them work. I have no idea why. This doesn't bother me much at the moment, because I don't really need these certs now, I have time. Please help me with problems 1 and 2. Also: when is the 3.1 public coming out? Is there a date yet? Thanks a lot for all your work, I appreciate it very much.
