I have the same error as described here: https://www.ads-software.com/support/topic/fatal-php-error-when-db-query-is-activated/
When I activate DB query which I need for debugging a slow site, I get this PHP error:
FastCGI: server “/usr/local/apache/cgi-bin/php7-fcgi80” stderr: PHP message: PHP Fatal error: Allowed memory size of 2147483648 bytes exhausted (tried to allocate 528384 bytes) in /wp-content/plugins/debug-objects/inc/class-db_query.php on line 275PHP message: PHP Fatal error: Allowed memory size of 2147483648 bytes exhausted (tried to allocate 10518400 bytes) in /wp-includes/functions.php on line 4212PHP message: PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0,
Can anyone help?

]]>debug objects works well in my multisite wordpress, except when i try to activate the “db query” option. it results in a fatal error on php.
from my php error log:
WordPress database error Query cache is disabled; restart the server with query_cache_type=1 to enable it para a consulta SET SESSION query_cache_type = OFF
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 2186187 bytes)
PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0Ref: debug-objects.php in __construct()
self::$table = $GLOBALS[ 'wpdb' ]->base_prefix . self::$table;
That continues to append the prefix resulting in the incorrect table name.
Example:
wp_hook_list
wp_wp_hook_list
wp_wp_wp_hook_list…
I tried to fix that but it seems some other error is encountered which causes the server to consume max memory. Have to deactivate until a new cut is available.
Thanks.

Hi,
As others have also pointed out, the plugin seems to not work properly, at its latest version (currently at v2.3.1).
I had the chance to troubleshoot and ultimately fix the issue, since I needed to use the plugin, so I’m sharing it here for others, and the plugin author as well.
Short answer:
Replace - 1 with 20 in debug-objects.php:225
Long answer:
It seems that the root cause is an error in the plugin’s initialisation sequence:
1. The static Debug_Objects::get_object() method is hooked at plugins_loaded with priority 10 (default), at debug-objects.php:28.
2. When it runs, it calls the constructor of Debug_Objects (debug-objects.php:86).
3. The constructor calls the Debug_Objects:init_classes() method (debug-objects.php:127).
4. The init_classes method schedules the intialisation of further classes, by hooking on plugins_loaded with priority -1.
Now, since the whole sequence was triggered by the plugins_loaded hook having already reached priority 10 (see Step 1), any action callbacks added to that hook with priority less than 11, are never executed.
A quick solution is to increase that priority to a number greater than 10 (see Short answer). That restored full plugin functionality in my case.
Does anyone know if this is working on 4.6.1? I am not getting any debug info with various settings and don’t know if the problem is with me or it…

Hello there,
I’m quite impressed by the options offered here but I’m a bit lost in settings…

]]>After running the plugin with different settings, I found out that there are lot of shortcodes that are being used/triggered unnecessarily on every page. It should be only on pages where they are required.
Also found out that there are lot of cron jobs that are not required at while others are set to aggressively.
My host sets my php memory limit at 128mb with 1gb ram and my site is using around 120mb. I need to reduce it. I am using 34 plugin including woocommerce and buddypress. I am using woocommerce for product comparison only but i can see shopping features like add to cart and other stuff being used and loaded so maybe that is also part of the puzzle.
Now I dont know how to take action and rectify this issue. I am not a developer nor an expert.
Is there a plugin for that too?
Thank you.

]]>Hello!
I know that sorting by query time via the feature list. However, the queries displayed for me are somewhat in order, but not completely from top to bottom. I’d like to see the most expensive queries on top across all queries.
It seems the queries ARE sorted by query time, but only in chunks. I also don’t see any tabs, buttons, anything that will sort the query information already displayed. I can dig into the code, but wanted to ask here first in case I’m missing something obvious.
Any help would be great! Thanks!
