[Plugin: WP Super Cache] Unable To Post With Version 0.9.3

Hi, I’m having a similar problem,
"Warning: Cannot modify header information - headers already sent by.."

I’m pulling out of wordpress the header and using it somewhere else. Is this possible whilst using wp super cache as well?

What’s the problem with the code?

Thanks,

You’ve probably got extra whitespace in /home2/sicanstu/public_html/pages/1024×768.php

Moved my website to a new host and everything seems OK except that I am getting this error message. Host telling me its a super cache problem and I need to disable it, but I can’t login to back end of site to disable. How do I manually disable super cache and solve the error message. site is https://www.design-confidential.com can’t bring up home page as super cache is pointing to old host site.
home/dbarrett/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php
Warning: Cannot modify header information – headers already sent by (output started at /home/content/d/e/b/deb10/html/designconfidential/wp-content/advanced-cache.php:1) in /home/content/d/e/b/deb10/html/designconfidential/wp-includes/pluggable.php on line 770

There’s probably extra whitespace n advanced-cace.php, did you edit that file to alter the path?

Hi I’ve just installed version 0.9.9

I am also getting the
<!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –>

when the path appears to be correct. this is how it reads (I have substituted example for my site name)

if ( !include_once( ‘CACHEHOME’ . ‘/home/.gallows/example/example.com/wp-content/plugins/wp-super-cache/wp-cache-phase1.php’ ) ) {
if ( !@is_file( ‘CACHEHOME’ . ‘/home/.gallows/example/example.com/wp-content/plugins/wp-super-cache/wp-cache-phase1.php’ ) )
register_shutdown_function( ‘wpcache_broken_message’ );

Also when I installed my .htaccess file was not altered. Is there specific code I should manually put in? the readme just says its should ‘similar’ to an example

I would really love to use this plug-in. Any help is most welcome, thanks

Yeah, scroll down the admin page, but the plugin has to be fully “ON” for it to show the rules.

implau – you should probably talk to your hosting support and ask them for the correct path. The plugin figures it out 99.999999% of the time but obviously not in your case (unless you just moved hosts?)

Thanks. I did that and going to try reinstalling on their request.

I feel like I have a completely run-of-the-mill set up, and yet this is seeming exceedingly complicated.

I reinstalled WP- supercache.
It seemed to alter the htaccess files correctly, it put the advanced-chache.php where they were supposed to be. I had to change the position of the define(‘WP_CACHE’, true); in the wp config file.

Now I don’t get any error messages, but no chaching, just nothing is going on ??

Oh. Now I changed the path on the advanced cache in wp-content and I’m back to getting the old

<!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –>

I used this path

if ( !include_once( ‘CACHEHOME’ . ‘/plugins/wp-super-cache/wp-cache-phase1.php’ ) ) {
if ( !@is_file( ‘CACHEHOME’ . ‘/plugins/wp-super-cache/wp-cache-phase1.php’ ) )
register_shutdown_function( ‘wpcache_broken_message’ );

thats not wrong. Right?

I’m afraid you’ll have to use the full path. It’s so early in the process/request that not much is defined.

Hi donncha,

So continuing my correspondence with my web host, they have determined that everything looks good from their end, after kindly assisting me in some issues with my wp-config file and even re-installing wp supercache on their end (as this was deemed to be a unique case). My job to finish the process was simply to enable the plugin. I did, choosing the options: ON, Cache rebuild, and Mobile device support, them hitting Update Status.

And still it appears not to work. I get 0 cached pages in the admin, no “dynamic page loaded” in the source code. The path defined by them (in my advanced-cache in wp content) is below, again with example instead of my site name.

if ( !include_once( ‘/home/.gallows/example/example.com/wp-content/plugins/wp-super-cache/’ . ‘wp-cache-phase1.php’ ) ) {
if ( !@is_file( ‘/home/.gallows/example/example.com/wp-content/plugins/wp-super-cache/’ . ‘wp-cache-phase1.php’ ) )
register_shutdown_function( ‘wpcache_broken_message’ );

My line of inquiry with my host regarding this issue is finished and I am hoping that you may have an idea about what could be going wrong

thanks very much

Anything in the debug log? Enable it in the admin page.

Here are the messages emailed to me from debug mode:
