W3 Total Cache Rotating Tweets = Not updating tweets?

(@optimisto)

This new version works as long as I am logged in WordPress (loading a non cached version of the site). If I log out and do not flush the W3TC cache, the plugin rotates the tweets from the W3TC cache and does not update until W3TC cache is updated.
This behavior is the same with basic or enhanced caching (Late Init. enabled in basic).
I described an issue with enhanced vs basic caching here. I am not using the default W3TC settings – is there an easy way to grab a summary of the settings, because they are probably over 50… I’m using a shortcode placed in the header, with the settings I posted here.

Do you have WP_DEBUG set to true?

If you have then there is an enormous section of HTML in the source which lays out the W3TC settings. The source also tells you (immediately after the Rotating Tweets HTML) whether W3TC is using the fragment cache or not.

For reference, my pgcache settings are:

For reference, if the caching works, you should see:

<!-- Rotating Tweets W3TC Fragment Caching Success ! -->

somewhere in your HTML source.

As far as I can tell from reading comments, I think fragment caching only works with ‘Basic’ Page Caching. For some reason, I can’t switch on Enhanced Caching so can’t test it unfortunately. Which method are you using? Are you seeing  in your HTML source?

If you are, then we may need to have the cached function take a more aggressive approach to updating the Tweets…

I’ve done a new version that is working for me – and loading new tweets much more frequently…

I don’t see a success string – should debug be on for that to appear?
This new version does not show up at all, just like it happened before.

What HTML is appearing on the source page?

What is the exact PHP you use to display the Tweets and which file have you put it in? Or are you entering it as a standard code or widget?

I’ve uploaded a version that doesn’t require WP_DEBUG to be set to TRUE before showing the message – although if WP_DEBUG is true you will get a lot more diagnostics to help solve the problem.

I already described what is the HTML here.
You can see here how I use the standard code.
I will test it again later with debug on.

Plugin Author

(@mpntod)

OK. Are you using a function to call the HTML or is it in a post?

Is it in a template file?

Does the caching work if you use a widget or a shortcode in a post?

Been looking at W3TC code. Apparently browser compression will also break the functionality…

The two variables to look out for are:

browsercache.enabled
browsercache.html.compression

I’ve updated the code to reflect this.

PS: You don’t need to set WP_DEBUG to see diagnostics now. If W3TC is set for debugging (on the Page Cache settings page) then Rotating Tweets will respect that too.

This is the page cache debugging.

This new version of the plugin shows up but does not refresh independently from the W3TC – bot as a shortcode in a post or in the header.php. I can not test it as a widget at this moment.

I am not sure how to get an answer for the rest of your questions.

Are you using a function to call the HTML or is it in a post?

Is it in a template file?
