Warnings on Admin Page
|
|
======================
|
|
|
|
Your ownCloud server has a built-in configuration checker, and it reports its
|
|
findings at the top of your Admin page. These are some of the warnings you
|
|
might see, and what to do about them.

Cache Warnings
|
|
--------------
|
|
|
|
"No memory cache has been configured. To enhance your performance please
|
|
configure a memcache if available." PHP has three caching extentions: APCu,
|
|
OPCache, and Xcache. You will see this warning if you have no caches installed,
|
|
and you may see it if you have APCu < 4.0.6 installed; older versions are
|
|
disabled because of performance problems.
|
|
|
|
If you see "APCu below version 4.0.6 is installed. for stability and
|
|
performance reasons we recommend to update to a newer APCu version" then you
|
|
need to upgrade, or, if you're not using it, remove it.
|
|
|
|
It is not required to use any caches, but caches improve server performance. See
|
|
:doc:`performance_tuning` for more information on installing and using caches.
|
|
|
|
You are accessing this site via HTTP
|
|
------------------------------------
|
|
|
|
"You are accessing this site via HTTP. We strongly suggest you configure your
|
|
server to require using HTTPS instead." Please take this warning seriously;
|
|
using HTTPS is a fundamental security measure. You must configure your Web
|
|
server to support it, and then there are some settings in the **Security**
|
|
section of your ownCloud Admin page to enable. The following manual pages
|
|
describe how to enable HTTPS on the Apache and Nginx Web servers.
