Hi @mbrsolution,
I do have the same issue as @owen919 – since yesterday evening.
Checked and tried everything:
logged in as admin
deactivated all others plugin
deactivated, deleted your plugin and installed a fresh copy
run “Optimize Database after Deleting Revisions”
…
If you have a solution please let me know. I would like to upgrade to your add-on plugin for subscription based stripe payment.
Thank you in advance
