Debug Profiling not working in prestashop 1.5.4

[quietkillah]

I am trying to improve the loading time of my website.

So after doing some modifications. I wanted to check the SQL Query speeds.

To do this i thought i only had to turn on Debug Profiling.

 

But when i change

define('_PS_DEBUG_PROFILING_', false);

to

define('_PS_DEBUG_PROFILING_', true);

 

part of my site doesn't get loaded. And i can't see any extra information.

I only see the toppart of my website.

 

Any ideas what is causing this issue? or how to resolve this?

Actually, it always worked this way for me. It's like the function has always been broken as far as I know!

Hmm, that's unlucky. And do you know of any alternatives to easily monitor your site speed (to be able to make some improvements?)

I tried using the mysql slow_query_log but it's quite hard to understand and analyse this log.

Well, prestashop 1.4 had some override classes for his, but they removed them from 1.5. Therefore, I'm honestly clueless about this

[quietkillah]

anyone else has some insight on this issue?

I you suggest to enable

define('_PS_MODE_DEV_', true);

to see if there are further errors in your installtion. Might be that there are missing db fields or something and therefore the profiler is not working.

Best regards, trip

can't seem to find any issues or errors in my installation, but it still doesn't work ...

I have the same problem.

I had the same problem with 1.6.0.9, my solution: 

 

Additionally to define('_PS_DEBUG_PROFILING_', true); in define.inc.php

edit tools/profiling/Controller.php and comment out the two lines (304-305 on 1.6.0.9):

/* if (!$this->ini_get_display_errors())
   return;
*/

Now it works. Don't know why ini_get_display_errors() is not initialized...

Plunckers answer did the trick on 1.5.5, thanks Pluncker

There is no such line in 1.6.1.4 and I have same issue. It just stopped working but I dunno why.

I only see blank page even if I have dev mode set to true.
