Refining the site in PHP

Hey! We need the help of a php specialist.
What work will need to be done:
- hide the broken section in the personal account (order miscalculation),
- correct the texts (there is a little),
- take some photos out,
- check the setting of notifications,
- check the retention of data of new registered users (currently, the data is not stored, it is impossible to collect leads).
