If you have used an older version of Codeus with no Visual Composer onboard and now you would like to edit your existing content with Visual Composers Frontend Editor, there is one step, that should be done for preparing this content to get it properly editable in Frontend Editor. This step is necessary to do, otherwise Visual Composer will cut off your text content once saved in Frontend Editor, because it is not inside VC text containers. This is a specificity of Visual Composer plugin and we don't have any influence on this.
Please note: if you don't want to use Frontend editor and would like to continue editing in classic mode using Shortcode Options (see below), you don't have to care about this step. So, the only thing you need to do is to include all your simple text content in VC text container.
Let's say you have previosly created a styled textbox with some text content inside. Your shortcode looks like this:
[text_box] My Text Content Goes Here [/text_box]
In order to get this text content to be properly editable in Frontend Editor and not to be lost after page update, you need to put your text in VC text container [vc_column_text]. So your textbox should look like this:
[text_box][vc_column_text]My Text Content Goes Here[/vc_column_text][/text_box]
Let's say you have a kind of this content:
[divider type='linebreak']
<h3 style="text-align: center;">Youtube Video</h3>
<img class="aligncenter size-full wp-image-3833" alt="photodune-4462514-opt" src="http://codex-themes.com/codeus/wp-content/uploads/2013/09/photodune-4462514-opt1.jpg" width="391" height="263" />
[youtube width="100%" height="495" video_id="6v2L2UGZJAM" style="style-6" position="middle"]
[divider type="double "]
<h3 style="text-align: center;">Vimeo Video</h3>
[divider type='linebreak']
In order to adjust it for Visual Composer, you need to include [vc_column_text] like this:
[divider type='linebreak']
[vc_column_text]
<h3 style="text-align: center;">Youtube Video</h3>
<img class="aligncenter size-full wp-image-3833" alt="photodune-4462514-opt" src="http://codex-themes.com/codeus/wp-content/uploads/2013/09/photodune-4462514-opt1.jpg" width="391" height="263" />
[/vc_column_text]
[youtube width="100%" height="495" video_id="6v2L2UGZJAM" style="style-6" position="middle"]
[divider type="double "]
[vc_column_text]
<h3 style="text-align: center;">Vimeo Video</h3>
[/vc_column_text]
[divider type='linebreak']
So as you see, everything concerning the simple text content should be included in [vc_column_text] container.
That's all. After including text content in VC text containers and saving your changes this page is available for comnfortable editing in Visual Composer Frontend Editor.
