LDC CoreTools Support

Solutions to Common Problems

CoreTools supports the following browsers:

  • Google Chrome
  • Safari
  • Firefox
  • Microsoft Edge
Since older versions of Internet Explorer do not support modern capabilities supported by other major browsers, we’ve discontinued support for Internet Explorer.

This can happen when firewalls, web filters, or other network infrastructure is impeding your connection to LDC CoreTools. Please check with your network administrators. They will need to provide you with access to these sites to solve the problem:

This can also happen if your network administrators have disabled web sockets.

On some rare occasions, attachments fail to load to our servers. This is commonly due to network connectivity problems that you may be experiencing. Unfortunately, when this happens we no longer have access to that resource. The solution is to delete the reference to the attachment in your module, attempt to re-upload it, and then re-export your module to PDF.
