error in cart proces

[emel]

VM version:3.2.14
Joomla: 3.8.7
rupostel one page checkout: 2.0.360.140318

Warning: str_replace() expects at least 3 parameters, 2 given in /home/users/arphnftp/WEBSITE/components/com_onepage/helpers/userfields.php on line 905

end of the page, the following can be read:
Deprecated: Non-static method OPCmini::printDebugMsgs() should not be called statically in /home/users/arphnftp/WEBSITE/components/com_onepage/overrides/virtuemart.cart.view.html.php on line 749

we've posted this question on the rupostel platform about 1 week ago, unfortunately without any reply so far.

regards

The messages are coming from com_onepage, and as you know Stan st Rupostel provides support for the extension.  You can probably turn off the warnings and deprecated messages, see http://forum.virtuemart.net/index.php?topic=102555.0
