A: http://[magento site]/api/v2_soap/index/ - error 500
B: http://[magento site]/api/v2_soap/index/wsdl/1/ - Working
Formerly the A is working to my old site which have 5.5 PHP version and now I migrated to another site which have 5.2 PHP version which cause the A: getting error 500 and now I'm using the B: which is working now. My concern is that there is a 3rd party connecting to the site which is using the A: and now there getting issue on getting any output from the site.
Thanks in advance
