Error loading references list from Zotero.

I love Bibbase, especially the latest theme, thanks for all your work on this.

I was hoping you could help with a recent - but increasingly frequent error. Occasionally when I load my publications page (https://pedrovale.bio.ed.ac.uk/publications) I get the following error message:

  • Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed in eval() (line 1 of /disk/data/www/drupal7/modules/php/php.module(80) : eval()'d code).
  • Warning: file_get_contents(): Failed to enable crypto in eval() (line 1 of /disk/data/www/drupal7/modules/php/php.module(80) : eval()'d code).
  • Warning: file_get_contents(https://bibbase.org/show?bib=https%3A%2F%2Fapi.zotero.org%2Fusers%2F837863%2Fcollections%2FM9VMJBQG%2Fitems%3Fkey%3DII3rucWmEcbdlGBRNINIxNWX%26format%3Dbibtex%26limit%3D100&theme=mila&owner=lastname&hidemenu=true): failed to open stream: operation failed in eval() (line 1 of /disk/data/www/drupal7/modules/php/php.module(80) : eval()'d code).

I've wondered if this is an issue with my Zotero library, but I can't see what the issue might be. I've used Bibbase using the same Zotero library for a few years and it's always worked very well. 

Any help appreciated!


Under review

My first suspicion would be that it is related to the expiration of Let's Encrypt's root certificate:


If so, then I think updating drupal or it's certificates may help, but I'm not sure and don't use drupal or php. You can also use the script-tag embedding option instead of the php embedding and that should solve the problem as well.


Thanks for the super quick response! Using the javascript option fixed the issue.
