Hello,
Thank you for your response.
Regarding the download file settings, the page templates are not selectable issue, I’d request you to check whether there are any plugins installed that might be causing this.
Here is what you can do to check:
1. Please try switching to another theme, like Twenty Twenty-one
, and check whether the issue persists or not. If not, then it is the theme that is causing the error.
2. Deactivate all plugins temporarily except WPDM and see if that solves the problem. Then, activate plugins one by one to see which plugin is causing the problem.
3. Try one more time after clearing your browser, website, and CDN caches if you have any. You may temporarily disable the caching plugin for testing.
Apart from that, to change the default link template layout you have to modify the related link template by following this instruction: https://www.wpdownloadmanager.com/doc/template-files/.
In the related template file, you can use any template tag you want and can customize it as per your need.
You may check our documentation for more details: https://www.wpdownloadmanager.com/doc/templates/template-tags/.
