OAI PMH Validation Failed

We get the following error on validation:

Checking Identify response

REQUEST https://grdspublishing.org/index.php/index/oai?verb=Identify GET

WARN Malformed response: syntax error at line 1, column 0, byte 0 at /usr/lib64/perl5/vendor_perl/XML/Parser.pm line 187. . The most common reason for malformed responses is illegal bytes in UTF-8 streams (e.g. the inclusion of Latin1 characters with codes>127 without creating proper UTF-8 mutli-byte sequences). You might find the utf8conditioner, found on the OAI tools page helpful for debugging.

FAIL Failed to parse Identify response

FAIL ABORT: Failed to parse Identify response from server at base URL ‘https://grdspublishing.org/index.php/index/oai’.

The OAI-PMH data provider with base URL https://grdspublishing.org/index.php/index/oai has failed initial validation. Problems reported must be corrected before validation can continue.

How to solve the problem?

Hi @grdspublishing,

I suspect there is something outside OJS that is preventing the OAI validation from working. If I look at your OAI page with a web browser, it works fine – but attempting to fetch it with another tool like wget results in a 403 Forbidden error. I suspect your web server is set up to deny requests depending on the user agent.
