Page load with error

I found this information

I would like to ask the Administration to comment on what this matter is about. Before the recent failure that prevented people using CloudFlare from entering the website, everything was working properly. Now, after the “repair”, the website no longer works properly, I get the above errors after logging in (CodeIgniter 4), and when I want to go directly to the link with the error, I get the following message

This site/page has used all avaialble php / apache processes allowed on free hosting account.
Refreshing the page once the amount of apache / php processes are reduced will cause the site to work
We would recommend upgrading your hosting account at IFastNet Premium hosting accounts , premium hosting accounts have MUCH higher resources dedicated to them.
