This article lists some common PHP Fatal Error quick examples that you could find when looking through your Adobe Commerce logs and the solutions for problems they indicate.

Example

‘PHP Fatal error: Maximum execution time of 60 seconds exceeded in…’

Solution

You can update the maximum execution time by setting a custom max_execution_time value in your php.ini file and redeploying.

For example:

max_execution_time = 120

Consult the Customize php.ini settings article.

Example

‘PHP Fatal error: Allowed memory size of 792723456 bytes exhausted’ (That’s just an example byte size.)

Solution

Customize your php.ini settings. Consult this Customize php.ini settings article.

Example

‘PHP Warning: Unknown: failed to open stream: No such file or directory’

Solution

Make sure you do not remove the Windows-style endings in the php.ini file. On Windows, line-endings are terminated with a combination of a carriage return (ASCII 0x0d or \r) and a newline(\n), also referred to as CR/LF.

Example

‘PHP Fatal error: Uncaught PDOException: SQLSTATE[HY000] [1040] Too many connections in’

Solution

The MySQL environment has run out of disk space. Provide more disk space for the MySQL environment.

Example

‘PHP Fatal error: Uncaught TypeError: Return value of Magento’

Solution

Check the <root>/tmp directory because it is probably full. If it is full, provide more space in the directory. This could involve simply moving files to another directory or deleting them.
