Hi,
I have a problem with OAI validation. I cannot cope with the problem
https://econjournals.sgh.waw.pl/KSzPP/oai?verb=Identify
Application Version - e.g., OJS 3.1.2.1
I tested at OAI-PMH Data Provider Validation and Registration
"REQUEST https://econjournals.sgh.waw.pl/KSzPP/oai?verb=Identify?verb=Identify GET
FAIL Server at base URL 'https://econjournals.sgh.waw.pl/KSzPP/oai?verb=Identify' failed to respond to Identify. The HTTP GET request with URL https://econjournals.sgh.waw.pl/KSzPP/oai?verb=Identify?verb=Identify received response code '500'.
FAIL ABORT: Failed to get Identify response from server at base URL 'https://econjournals.sgh.waw.pl/KSzPP/oai?verb=Identify'."
and http://oval.base-search.net/
"Validation Results

http://validator.oaipmh.com/ the test is ok.
How can I fix the problem?
