Bulk Invoice download failed


when i try to use the bulk download function, i receive the “Whoops, looks like something went wrong.” error, and in the apache log i’ve found this entry:
[Thu Sep 07 15:13:26.984476 2017] [fcgid:warn] [pid 28124:tid 139976657532672] [client] mod_fcgid: stderr: PHP Fatal error: Call to undefined function Barracuda\ArchiveStream\gmp_init() in /xxx/xxxxx/xxxx/xxxxxxx/public_html/vendor/barracudanetworks/archivestream-php/src/ZipArchive.php on line 108, referer: https://invoice.xxxxx.xxx/invoices

how can I fix this?

thank you in advance


It looks like you need to enable the GMP PHP extension.

OK, it works now.

Thank you!
