I found a way to resolve it:
- I installed and activated Plugin Organizer WP Plugin
- Used Settings:
- Fuzzy URL matching = ON
- Ignore URL Protocol = ON
- Ignore URL argument = ON
- Auto trailing slash = ON
- Selective Plugin Loading = ON (very important)
- Selective Admin Plugin Loading = ON (very important)
- Created a new plugin filter with the permalink http://example.org/wp-admin/admin.php?page=formidable-entries
- Checked “Also Affect Children” in the plugin filter page
- Disabled Payment Forms for Paystack in the list of plugins in the filter page
- Saved and that solved it for me
This took me weeks of almost losing my mind!!! Hopefully the above helps others
