Hello, it may be due to your server’s PHP configuration. Could you please edit the .htaccess file to add this rule?: php_value output_handler none, it should look something like:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
php_value output_handler none
# WordPress rewrite rules down here
[...]
</IfModule>
# 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.
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.
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:
<?php
echo "<h1>Handlers</h1>";
var_dump(ob_list_handlers());
echo "<h1>Output Buffering</h1>";
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.
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.
Now I want you to do something, could you please add to that file this:
if( ini_set('output_buffering',4096) === FALSE ) {
echo "<h1>Can't Set</h1>";
}
/* This is the same as before */
echo "<h1>Handlers</h1>";
var_dump(ob_list_handlers());
echo "<h1>Output Buffering</h1>";
var_dump(ini_get('output_buffering'));
Let’s see if your server allows you to activate the output buffering.
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
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"
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?
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!
Great news, I’m glad you got it working. Feel free to contact me again if you find any other issue.
Best regards.
