EDIT: I solved these issues by uninstall and re-installing GravityForms.
Would appreciate to know why this happened...
I got two major issues with entries:
I have setup a test form, filled the required values, submitted, and I received the email with the correct data. But when I go to Forms > Entries, the list is empty for some reason. I also checked the database via phpMyAdmin and the form data seems to be there under wp_rg_lead_detail table, but they don't appear under Entries in the Dashboard. Also, under Edit Forms, in Entries column, it shows '0' in in the form I submitted.
The second problem I'm having is even stranger.
I have additional from (total of 2 forms), that is configured in a different page than the first form.
When I submit the 1st form, and I check the database in wp_rg_lead_detail table, I see the default field values from the second form too... no idea why...
The email itself contains only data from the actual form I submitted.
Thanks in advance
