I've upgraded my php to 7 since my pci compliance scan said I needed to. So now my site is not working properly at all. I've tried a few edits from others and nothing is helping.
The product, orders and customers tables are not showing. The heading is there but nothing under them.
Edited to add: The tables are not showing on the front end either. Header, template and category selection is working fine. No products show just an empty page between the header and footer.
Thank you in advance for your help.
