Certificate image is saved as blank

[loris_s]

Hi, if I regenerate a certificate (by opening it as https://www.ideaeduca.com/members/loris_santamaria/?regenerate_certificate) and then click on the certificate, it displays ok, and I can show it as a PDF and I can print it. The problem is that the generated image is blank (empty jpeg) and the next time I open the user profile (https://www.ideaeduca.com/members/loris_santamaria/) the certificate won't work. I've already created an exception for the certificate image ({uploads_dir}/2018/01/Certificado5.png ) in W3C Total Cache. Please help

Well please make sure that GD image library is enabled on your server . Contact your webhost on this . also ask them if they have any kind of security enabled which disables posting of any base64 encoded files on server .

Please also share your server php error log and a valid ftp credentials to debug this .

Credentials that you shared are wp admin credentials . Well I would need FTP credentials to check this issue .

Sorry I cannot give you ftp credentials on this site. Let me know which php script should I debug and how would you recommend to debug it. Thanks

Well I am not sure , I would need to check numerous number of files in your site and for that I would need your site ftp credentials . Please share them if you want us to help .

weirdly enough, I had to set define( 'FS_METHOD', 'direct' ) in wp-config.php. Now certificate images are saved correctly
