Live preview not automatically updating

Question

any help would be much appreciated.

I have Live Preview working on my entries ie. I can see and use the button, but the live preview won't update as I manipulate the content? It was working before so it is baffling me as to how it could stop working.

The only change I think I have made in that time is removing the open_basedir settings in my php.ini, but I wouldn;t imagine that would affect it?

Thanks,

Dc

UPDATE::

This is the htaccess code:

<IfModule mod_rewrite.c>
    RewriteEngine On

    # Send would-be 404 requests to Craft
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
    RewriteRule (.+) index.php?p=$1 [QSA,L]
</IfModule>

Answer 1

There is a known issue where if you use a variable name 'entry' in any template involved in a Live Preview request (including layout templates), then it can cause the behavior you're seeing.

Some examples are:

{% set entry = craft.entries. ... .find() %}

or

{% for entry in craft.entries. ... .find() %}

The workaround is to rename that variable to something else. myEntry, for example.

Be sure to look for JavaScript errors as well! I was having the same trouble with a CloudFlare-enabled site, and it turned out that the Rocket Loader feature was choking and keeping previews from working properly. Otherwise no entry variables in play.

Brad & Matt provided good suggestions, but we just found another case where this can happen – when using matrix blocks with special filters or conditions.

In Craft 2.6 I found that this line does not update during Live Preview, but instead uses the last saved revision:

{{ entry.banner.type('bannerContent').first().bannerTitle }}

Whereas this line works fine:

{{ entry.banner.first().bannerTitle }}
