### Why do I get warnings about SSL certificates?

SSL (Secure Socket Layer) is a technology to encrypt data transfer between computers.
Sometimes your browser warns you about a missing or invalid certificate.
These warnings can have three reasons:

1. The server you are connected to doesn't offer SSL encryption.
2. The server has a self-signed certificate (not recommended).
3. The certificate is expired.

We recommend to talk to the admin(s) of the affected friendica server. (Admins, please see the respective section of the [admin manual](help/SSL).)

<a name="upload"></a>
### How can I upload images, files, links, videos and sound files to posts?

You can upload images from your computer using the [editor](help/Text_editor).
An overview of all uploaded images is listed at *yourpage.com/photos/profilename*.
On that page, you can also upload images directly and choose if your contacts will receive a message about this upload.

Generally, you can attach any kind of file to a post.
This is possible by using the "paper-clip"-symbol in the editor.
These files will be linked to your post and can be downloaded by your contacts.
But it's not possible to get a preview for these items.
Because of this, this upload method is only recommended for office or zipped files.
If you want to share content from Dropbox, Owncloud or any other [filehoster](http://en.wikipedia.org/wiki/Comparison_of_file_hosting_services), use the "link"-button (chain-symbol).

When you're adding URLs of other webpages with the "link"-button, Friendica tries to create a small preview.
If this doesn't work, try to add the link by typing: [url=http://example.com]*self-chosen name*[/url].

You can also add video and audio files to posts.
However, instead of a direct upload you have to use one of the following methods:

1. Add the video or audio link of a hoster (Youtube, Vimeo, Soundcloud and anyone else with oembed/opengraph-support). Videos will be shown with a preview image you can click on to start. SoundCloud directly inserts a player to your post.

2. If you have your own server, you can upload multimedia files via FTP and insert the URL.

Friendica uses HTML5 for embedding content.
Therefore, the supported files are dependent on your browser and operating system.
Some supported file types are WebM, MP4, MP3 and OGG.
See Wikipedia for more of them ([video](http://en.wikipedia.org/wiki/HTML5_video), [audio](http://en.wikipedia.org/wiki/HTML5_audio)).

<a name="avatars"></a>
### Is it possible to have different avatars per profile?

Yes.
On your Edit/Manage Profiles page, you will find a "change profile photo" link.
Clicking this will take you to a page where you can upload a photograph and select which profile it will be associated with.
To avoid privacy leakage, we only display the photograph associated with your default profile as the avatar in your posts.

<a name="language"></a>
### How can I view Friendica in a certain language?

You can do this by adding the `lang` parameter to the url in your url bar. The data in the parameter is a [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) code. eg. https://social.example.com/profile/example translated in German becomes https://social.example.com/profile/example?lang=de. If the question mark is already in the url you need to do it using a ampersand. eg. https://social.example.com/profile/example?tab=profile becomes https://social.example.com/profile/example&lang=de.

When a certain language is forced, the language remains until session is closed.

<a name="contacts"></a>
### What is the difference between blocked|ignored|archived|hidden contacts?

We prevent direct communication with **blocked contacts**.
They are not included in delivery, and their own posts to you are not imported.
However their conversations with your friends will still be visible in your stream.
If you remove a contact completely, they can send you another friend request.
Blocked contacts cannot do this. They cannot communicate with you directly, only through friends.

**Ignored contacts** are included in delivery - they will receive your posts and private messages.
However we do not import their posts or private messages to you.
Like blocking, you will still see this person's comments to posts made by your friends.

An addon called "blockem" can be installed to collapse/hide all posts from a particular person in your stream if you desire complete blocking of an individual, including his/her conversations with your other friends.

An **archived contact** means that communication is not possible and will not be attempted.
(Perhaps the person moved to a new site and removed the old profile.)
However unlike blocking, existing posts this person made before being archived will be visible in your stream.

A **hidden contact** will not be displayed in any "friend list" (except to you).
However a hidden contact will appear normally in conversations and this may expose his/her hidden status to anybody who can see the conversation.

<a name="removed"></a>
### What happens when an account is removed? Is it truly deleted?

If you delete your account, we will immediately remove all your content on **your** server.

Then Friendica issues requests to all your contacts to remove you.
This will also remove you from the global directory.
Doing this requires your account and profile still to be "partially" available for up to 24 hours in order to establish contact with all your friends.
We can block it in several ways so that it appears empty and all profile information erased, but will then wait for 24 hours (or after all of your contacts have been notified) before we can physically remove it.

After that, your account is deleted.

<a name="hashtag"></a>
### Can I follow a hashtag?

Yes. Simply add the hash tag to your saved searches.
The posts will appear on your network page.
For technical reasons, your answers to such posts won't appear on the "personal" tab in the network page and the whole thread isn't accessible via the API.

<a name="rss"></a>
### How to create a RSS feed of the stream?

If you want to share your public page via rss you can use one of the following links:

#### RSS feed of your posts

	basic-url.com//feed/[nickname]/posts

Example: Friendica Support

	https://forum.friendi.ca/feed/helpers/posts

#### RSS feed of the conversations at your site

	basic-url.com/feed/profilename/comments

Example: Friendica Support

	https://forum.friendi.ca/feed/helpers/comments

<a name="clients"></a>
### Are there any clients for friendica I can use?

Friendica is using a [Twitter/GNU Social compatible API](help/api), which means you can use any Twitter/GNU Social client for your platform as long as you can change the API path in its settings.
Here is a list of known working clients:

* Android
  * [Friendiqa](https://github.com/lubuwest/friendiqa) (available in Google Playstore or from a binary repository you can add to [F-Droid](https://freunde.ma-nic.de/display/3e98eba8185a13c5bdbf3d1539646854))
  * AndStatus
  * Twidere
  * Mustard and Mustard-Mod
* SailfishOS
  * [Friendly](https://openrepos.net/content/fabrixxm/friendly#comment-form)
* Linux
  * Hotot
  * Choqok
* MacOS X
  * Hotot
* Windows
  * [Friendica Mobile](https://www.microsoft.com/de-DE/store/p/friendica-mobile/9nblggh0fhmn?rtc=1) for Windows 10
  * Hotot

Depending on the features of the client you might encounter some glitches in usability, like being limited in the length of your postings to 140 characters and having no access to the [permission settings](help/Groups-and-Privacy).

<a name="adminaccount2"></a>
### Can there be more then one admin for a node?

<a name="dbupdate">
### The Database structure seems not to be updated. What can I do?

Please have a look at the Admin panel under [DB updates](/admin/dbsync/) and follow the link to *check database structure*.
This will start a background process to check if the structure is up to the current definition.

You can manually execute the structure update from the CLI in the base directory of your Friendica installation by running the following command:

    bin/console dbstructure update

if there occur any errors, please contact the [support forum](https://forum.friendi.ca/profile/helpers).
