We are a WordPress website agency, and we have a client site using the free version of Download Manager. It was working fine until a couple of months ago, when users trying to download files with a password started inconsistently seeing an “Invalid Download Link” error.
We initially thought it was a caching issue and excluded the download page from Edge full-page caching, but it did not resolve the issue. We are wondering if it has to do with the “Lock Options” since the client has been using password-required downloads on the free version, but from your documentation it seems that should work fine, and the restriction is on setting a specific number of times that the password can be used. Is that correct?
Are there any other known issues with DIVI or plugin incompatibilities that may cause the “Invalid download link” issue?
