Could you please edit the .htaccess file to add this rule?: `php_value output_handler none`, it should look something like: * ``` # BEGIN WordPress RewriteEngine On php_value output_handler none # WordPress rewrite rules down here [...] # END WordPress ``` * Apparently there are some output handlers that doesn’t work well with output stacking. Please test this and let me know how it goes. * Cheers. * Thread Starter [mcmikemn](https://wordpress.org/support/users/mcmikemn/) * (@mcmikemn) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3596984) * Thanks for the fast response! * That, unfortunately, did not help, though. I added the value to .htaccess and reloaded the website, but still got the error. * Plugin Author [Jose Luis SAYAGO](https://wordpress.org/support/users/iluminatus/) * (@iluminatus) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597026) * What bothers me is on line 1045 there’s no `ob_start()`. Could you please make a test in your server? upload a test.php file with this content: * ``` Handlers"; var_dump(ob_list_handlers()); echo "

Output Buffering

"; var_dump(ini_get('output_buffering')); ?> ``` * Then paste here the results. Output errors are difficult to debug because they’re related to different php configurations. * Thread Starter [mcmikemn](https://wordpress.org/support/users/mcmikemn/) * (@mcmikemn) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597039) * results: * ``` Handlers array(0) { } Output Buffering string(1) "0" ``` * And that’s with the .htaccess file still edited to contain the “php_value output_handler none” line. * Plugin Author [Jose Luis SAYAGO](https://wordpress.org/support/users/iluminatus/) * (@iluminatus) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597047) * Now I want you to do something, could you please add to that file this: * ``` if( ini_set('output_buffering',4096) === FALSE ) { echo "

Can't Set

"; } /* This is the same as before */ echo "

Handlers

"; var_dump(ob_list_handlers()); echo "

Output Buffering

"; var_dump(ini_get('output_buffering')); ``` * Let’s see if your server allows you to activate the output buffering. * Thread Starter [mcmikemn](https://wordpress.org/support/users/mcmikemn/) * (@mcmikemn) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597073) * Can’t Set * Plugin Author [Jose Luis SAYAGO](https://wordpress.org/support/users/iluminatus/) * (@iluminatus) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597082) * I’m wondering, do you have access to the **php.ini** file? If so, could you please set the output_buffering to 4096 like this: * ``` ; a value for this directive (e.g., output_buffering=4096). output_buffering = 4096 ``` * It would be nice if you can check the `memory_limit` it’s recommended to be at least 128M * Thread Starter [mcmikemn](https://wordpress.org/support/users/mcmikemn/) * (@mcmikemn) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597131) * I found how to control my own php.ini under Dreamhost, and configured it to raise the memory limit to 128M and output buffering to 4096. I still get the error, though. * Here is my current test.php output: * ``` Can't Set Handlers array(1) { [0]=> string(22) "default output handler" } Output Buffering string(4) "4096" ``` * Plugin Author [Jose Luis SAYAGO](https://wordpress.org/support/users/iluminatus/) * (@iluminatus) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597132) * Hi, it can’t be set because your PHP configuration is using admin flags which avoids rewriting php.ini parameters. However, you’ve already set the handlers through the php.ini configuration file. * Have you tested the plugin to see if it keeps displaying the same fatal error? * Thread Starter [mcmikemn](https://wordpress.org/support/users/mcmikemn/) * (@mcmikemn) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597133) * I thought that it did and it failed again, but I tested yet again right now and it seems to work fine. Thanks for walking me through the fix! * Plugin Author [Jose Luis SAYAGO](https://wordpress.org/support/users/iluminatus/) * (@iluminatus) * [13 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-698/#post-3597135) * Great news, I’m glad you got it working. Feel free to contact me again if you find any other issue. * Best regards.
