KnowledgeTree Checkup
KnowledgeTree Checkup
This checkup allows you to check that your environment is ready to
support a KnowledgeTree installation, and that you can proceed to
configure your system. Red items are things to fix. Orange items means
you may not be having the ultimate experience unless the support is
added. Green items means you're ready to go in this area. You can
check back here to see if anything has changed in your environment if
you have any problems.
.htaccess file
You can let KnowledgeTree manage the PHP settings that apply to the
KnowledgeTree application (it won't affect your other applications) by
configuring your web server to use the .htaccess files that come with
KnowledgeTree. This will ensure that the settings for KnowledgeTree
(detailed below) are set up for optimal, reliable performance.
