Hello,
Thank you for writing to us.
We have tested with the latest version of WPDM and it appears that there is no such error appearing.
We’ll need to take a closer look to see why this might be happening. But, this might take a little longer. Therefore, 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.
This is a general debugging process that all WordPress support teams perform to find 90% of the problems.
If you are not sure how to go about it, we’ll be glad to help. Please share your website credentials as mentioned below so that we can take a look and help you asap.
