Problem turning invoice into pdf

[jpennington]

I am unable to print or email invoices. I am up to date on everything, espocrm and advance pack.

When I try to print an invoice I get a blank webpage vs a pdf.

when I try to email an invoice I get a 500 error.

i have no idea of how to fix this issue. My espocrm is installed on an amazon server.

Hello,
could you check espocrm log (data/logs) and server error log?

Here is what I found

set permition to data folder 775
also to know the reason of 500 error, check server error log, if it's possible

[jpennington]

I tried:

sudo chmod -R 775 /var/www/espocrm/data

Problem still persist. Any ideas?

[tanya]

Without log, which can show the error reason, is really hard to help you

[jpennington]

I found it in a log:

What php version do you use?

"Documentation says that JSON_PRESERVE_ZERO_FRACTION is 'Available since PHP 5.6.6.'"

[jpennington]

Got it fixed. I had to update php. Thank you for help!
