When trying to load customers infos under admin-customers-customers file or under orders-customers-customers info, an sql request causes the entire site (front end and admin) where we get a 503 error. I believe it to be an sql query from a module but I have no clue where to find an sql error log...
Debug mode causes a 500 internal error ONLY on the admin side with a symphony error on the server error log. Front OK.
Debug mode off- 503 error on both admin and front after a very long page load like 2-3 minutes.
Host provider says caused by sql query but I do not know where to look for the error.
Wasn't there a tool in chrome or firefox that could track query time?
Any suggestions?
