Hi InvestorComps,
Thank you for reaching out!
We found this article in PMPro support that seems to be related to your issue: PMPro Login Page Doesn’t Work.
In this topic, the PMPro author mentioned it might probably be caused by some conflicting third party plugin or the theme itself.
We were not able to replicate this issue. For this reason, we don’t think it is related to our theme. However, to be sure, could you change your theme for a standard WP theme like Twenty-Twenty? Then, could you try to see if you’re still facing this issue, please?
If yes, could you switch back to Cera and deactivate all plugins that have not been installed with your theme during its setup and all existing custom PHP code snippets please? And then, could you confirm me that the issue is still persisting please?
Please also make sure that you have the latest theme version and that all recommended plugins are up-to-date. Finally, you could also consider clearing all activated caching system as well as your browser cache before investigating any further. If you want to read more on what browser cache is and how to clear it, here is an article that might help you: How to Clear Internet Cache in Every Major Browser.
Thank you.
