hi!
at the end of any order with One Page Checkout for Virtuemart 2 ,it shows the below warnings:

Warning: array_push() [function.array-push]: First argument should be an array in /home/googla/public_html/libraries/tcpdf/tcpdf.php on line 21357

hello, we recommend to disable Error reporting in Joomla global configuration. This error is not caused by OPC file, but by the tcpdf which is used to create pdf invoices. You may need to update to the latest VM release to fix this issue, or check with your other order processing extensions (vmee, artio invoice and similar).

Best Regards,
Stan

ok, np, would you mind if i fix this directly on your site with an ftp access? it would be much better for me to copy your configuration and see this warning on my demo servers, but this can be very specific to your configuration. please send me an email to info@rupostel.com
