fpdf not working for me on unbuntuu 20.04

I have recently setup a new LAMP server, everything is working fine for my webapp except when trying to export files using fpdf. It worked fine on my other hosting provider but I cannot get it to work here. I get a “This page isn’t working” “xxxxxx is currently unable to handle this request” “HTTP ERROR 500”

Is there some web configuration I have overlooked to allow this to work ?

Hi @JamesAus,

I would recommend checking out your error logs. The information should be displayed there as to why it’s not working and it’s giving you this one.

Usually, the HTTP ERROR 500 is related to the code itself rather than the server so you’ll need to create a php error_log and recreate the issue. Once the issue is recreated the error will be logged in the file you’ve created. To enable PHP error logging, you need to set two directives in your php.ini file:


First, use a text editor to set the log_errors directive as shown:

log_errors = On

Next, set the error_log directive to log PHP errors to a specific file. Replace path with the path to the log file, and filename with the log filename:

error_log = /path/filename

That’s it, you now have the error log enabled.
