- Plesk for Linux
Note: the article is related to the issue that occurs after Apache upgrade (during dist-upgrade for example).
After failed Plesk upgrade on Debian OS with Apache version 2.4 installed, web server is not starting. The following error messages appears:
CONFIG_TEXT: apache2: Syntax error on line 234 of /etc/apache2/apache2.conf: Syntax error on line 5 of /etc/apache2/conf.d/zz010_psa_httpd.conf: Syntax error on line 72 of /etc/apache2/plesk.conf.d/server.conf: No matches for the wildcard '*.conf' in '/etc/apache2/plesk.conf.d/ip_default', failing (use IncludeOptional if required)
