Update does not work

[netsecuris]

I try to update Espo from version 4.2.7 to 4.3.1. I download the zip. I browse to the file. I click Upload button. Page says Uploading but then it just quits. Still stuck at version 4.2.7. What can i do to solve this problem.

There was more to that first log entry but it was so log it was hard to capture so I have attached the logfile.

I see, you have good enough max memory size value, but try to increase it to 512M and restart the server
