Problem with confirming order, error 500

[zarza]

Hello,

After I complete my order, select payment option as cash on delivery, and click on confirm, I get an error 500. Weird thing is, the order is recognized and I can see it in back office. After going to config/define.inc.php and change define('_PS_MODE_DEV_', false); to define('_PS_MODE_DEV_', true); I now get this error message :

Fatal error: Uncaught exception 'ImagickException' with message 'WriteBlob Failed `/nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/cache/tcpdf/mska_ffa6f886f52a57d3970c68e13054fd7c' @ error/png.c/MagickPNGErrorHandler/1643' in /nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/tools/tcpdf/tcpdf.php:8618 Stack trace: #0 /nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/tools/tcpdf/tcpdf.php(8618): Imagick->writeimage('/nfsmnt/hosting...') #1 /nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/tools/tcpdf/tcpdf.php(8078): TCPDF->ImagePngAlpha('/nfsmnt/hosting...', 10, -26.8523055556, 178, 103, 60.9654800433, 35.2777777778, 'PNG', '', 'B', false, 300, '', 'ffa6f886f52a57d...') #2 /nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/tools/tcpdf/tcpdf.php(23818): TCPDF->Image('/nfsmnt/hosting...', 10, -26.8523055556, 60.9654800433, 35.2777777778, '', '', 'B', false, 300, '', false, false, 0, false, false, true) #3 /nf in /nfsmnt/hosting1_2/7/c/7c4eb405-0fec-4a85-a648-5a6295c17e81/zarza.sk/web/tools/tcpdf/tcpdf.php on line 8618

 

I cant make any sense of this. Any help is appreciated.

Hello,

Probably this answer comes too late but anyway: I had the same error, the problem occurs when the invoice PDF to be send via mail is written in the cache directory. You should check your permissions on web/cache/tcpdf, that fixed my problem.
I hope this helps someone.
