Hi.. After few hours of reading forum and tutorials I decide to ask from help.. I followed tutorial from this site: https://www.howtoforge.com/tutorial/perfect-server-debian-8-jessie-apache-bind-dovecot-ispconfig-3/ I'm using latest ver of ISPConf v126.96.36.199p8 on Debian v8.2 x64 I build the site and it working OK. But when I login as admin and goes to SITES -> UPDATE PACKAGELIST and select from AVIABLE PACKAGE of any app after ~10-15min of status message: Installation_task it generate me error message Installation_error! Same is if I login as user (owner of site) and try to install for example WordPress app. This is on psyhical macheine but I try on Virtual box to repeat angain installation and have a same problem. Site is generated with next parameters: SuEXEC -> ticked Own Error-Documents -> ticked PHP -> Fast CGI PHP Version -> Deafault If I install manualy for example WordPress to my site as client I can connect to MySql database and everything working. All services running without problem. I try to remove manualy over ssh all zip files from /usr/local/ispconfig/interface/web/sites/aps_meta_packages/ and generate again, but without success. Can anyone gave me some suggestion what can I do? What type of log do I need to read to understand where is the problem?
