php - WKPDF system error? -

i'm trying figure out pdf files beingness generated wkpdf.php file.

here's email when fail (which every time):

wkpdf scheme error: <pre>loading pages (1/6) [> ] 0% [======> ] 10% [=============> ] 23% [===================> ] 32% [============================> ] 47% [============================> ] 48% [===============================> ] 52% warning: ssl error ignored [===============================> ] 52% [===============================> ] 53% [=================================> ] 55% [==================================> ] 57% [===================================> ] 59% [=======================================> ] 66% [========================================> ] 68% [===========================================> ] 72% [==============================================> ] 78% [================================================> ] 81% [============================================================] 100% counting pages (2/6) [============================================================] object 1 of 1 resolving links (4/6) [============================================================] object 1 of 1 loading headers , footers (5/6) printing pages (6/6) [> ] preparing [============================================================] page 1 of 1 done </pre> /dashboard/submit/overview array ( [info1] => pdf [attached_stuff] => 0 [more_info] => [stackoverflow] => exact [other_data] => [sample_fields] => array ( [0] => option1 [1] => option2 [2] => option3 ) [test_option] => url [last_test] => asc )

here's line php file that's sending error in case helps:

if(strpos(strtolower($this->pdf['stderr']),'error')!==false)throw new exception('wkpdf scheme error: <pre>'.$this->pdf['stderr'].'</pre>');

a bunch of people have talked similar issues related using wkpdf ssl, don't think that's causing problems since says ssl error ignored... help appreciated. whenever seek doing it, there appears 500 error occurring can't find reason happening...

let me know if more info needed.
