SyntaxError Fatal error during upgrading 3.0.2 to 4.1.0

Dears, I tried upgrade my 3.0.2 to 4.1.0 (due to PHP8.0 issue)
Upgrade Progress stucked at "Patch 2 has been applied (2 of 9)"
and I found:
SyntaxError: Unexpected token '<', "<br />
<b>"... is not valid JSON
parsererror
<br />
<b>Fatal error</b>: Maximum execution time of 60 seconds exceeded in wwwroot\system\library\db\mysqli.php on line 99

even I modified max_execution_time in php.ini to 300

any idea please? thanks

You will need to ask your host how to change max_execution_time. You may be better upgrading to 3.0.4.0 which is compatible with PHP 8 and more stable.

thanks a lot ADD Creative, I will try
