If I install the newest version of the OPC plugin it fixes a few other bugs but totally breaks my payment plugin. I get this in the error logs:
PHP Warning: fread() expects parameter 1 to be resource, boolean given in /public_html/plugins/vmpayment/linkpoint/linkpoint.php on line 374
PHP Warning: fclose() expects parameter 1 to be resource, boolean given in public_html/plugins/vmpayment/linkpoint/linkpoint.php on line 375
Any ideas?
