wp super cache + nginx no footer comment?

Do the comments show up when WP Super Cache is deactivated?

Hi,
Thanks for the response. I’m talking about the super cache comment (which can show if it’s working) if it wasn’t clear, but I’ll try deactivating it and see.

True. I was confused about what you mentioned as “footer comment”. Obviously, it wouldn’t show up if the plugin is deactivated. Probably, another plugin strips off any HTML comment in the generated content. However, I believe it is inserted by WP Super Cache after the generation of content.

You may check the following areas…

At your site’s /wp-admin/options-general.php?page=wpsupercache&tab=debug, please see if the option (‘Cache Status Messages’) is enabled (checked).

At your site’s /wp-admin/options-general.php?page=wpsupercache&tab=plugins , please see, if you have any (minify) plugins that are enabled. There used to be a famous (add-on) plugin for WP Super Cache to minify HTML.

Hi,
Looking in the logs generated by super cache, it looks like some plugin or theme is calling ob_start but not ob_end_flush. I found a possible hacky workaround by putting this at the bottom of your theme’s footer.php:

<?php
while(ob_end_flush()) {} ?>

However, that didn’t seem to solve it. Any idea how I might be able to figure out if this is indeed the issue, and if so, which plugin is causing it?
Thanks,
-Michael.

Sorry, no idea on how things with ob_start or with ob_end_flush. Probably, you may setup a development environment and try deactivating the plugins one by one to find the one that causes conflict.
