How to understand what is wrong in Joomla requests?

Question

Joomla

Hello!
I have one client hosted, the site on Joomla lesparksad.ru, the attendance was cheap, everything was ok, then the owner found a programmer who finalized some small functionality, and now we regularly have: User 'lespark1_lpsa' has exceeded the 'max_questions' resource (current value: 250000) SQL=INSERT INTO `kn12dv_session` (`session_id`, `client_id`, `time`) VALUES ('j7pk56t9qk70a5mt56khk0ioni60', 0, '152393921514')
250000 - that's a lot....
I know for VP there is convenient palagin wp qery monitor - shows heavy queries and full information. Is there something similar for Joomla? The programmer says he tried everything, and optimize and cache recommendations in the internet.

Answer 1

Enable logging of slow MySQL queries and look in the log for the reason for exceeding the limits and take measures to optimize queries. Is caching enabled on the site? I recommend enabling caching both in the global Joomla settings and in running modules and components, where possible.

Answer 2

Joomla has a debug mode that will show all the information of all requests. Eliminating this error specifically - disable the session handler in Joomla in the general settings.
