Hi, I have just upgraded Ubuntu from 12.04 to 14.04, which also changed apache 2.2 to 2.4. Interface is running and I'm trying to do a resync, to get the websites up to apache 2.4 syntax, but it is not working. Ispconfig produces a lot of .vhost.err files in "sites-available" Up until now it has been a pain, but now I think I'm closing in on my issue. It seems that the file: apache2_plugin.inc.php from ISPconfig comes with some Apache 2.2 syntax for enabling webDAV. (search for "Allow,Deny") I have changed it to 2.4 syntax, but this will probably become a problem the next time ISPconfig is updated. Can someone confirm that this is indeed the only way to solve this issue currently?
